Stephen and I visited Cahir Castle in June 2022, and I was very impressed. I had no idea that we have such an old castle in Ireland with so much intact.
From the OPW website https://heritageireland.ie/visit/places-to-visit/cahir-castle/:
“Cahir Castle is one of Ireland’s largest and best-preserved castles. It stands proudly on a rocky island on the River Suir.
The castle was was built in the thirteenth century and served as the stronghold of the powerful Butler family. [The Archiseek website tells us it was built in 1142 by Conor O’Brien, Prince of Thomond] So effective was its design that it was believed to be impregnable, but it finally fell to the earl of Essex in 1599 when heavy artillery was used against it for the first time. During the Irish Confederate Wars it was besieged twice more.
At the time of building, Cahir Castle was at the cutting edge of defensive castle design and much of the original structure remains.“
Our tour guide took us through the castle as if we were invaders and showed us all of the protective methods used. We were free then to roam the castle ourselves.
The name derives from the Irish ‘an Chathair Dhun Iascaigh’ meaning stone fort of the earthen fort of the fish.
The information leaflet tells us that the area was owned by the O’Briens of Thomond in 1169 at the time of the Anglo-Norman invasion. The area around Cahir was granted to Phillip of Worcester in 1192 by John, Lord of Ireland, who later became King John. His nephew William was his heir – I’m not sure of his surname! But then his great-granddaughter, Basilia, married Milo (or Meiler) de Bermingham (he died in 1263). They lived in Athenry and their son was the 1st Lord Athenry, Piers Bermingham (died 1307).
Edward III (1312-1377) granted the castle to the James Butler 3rd Earl of Ormond in 1357 and also awarded him the title of Baron of Cahir in recognition of his loyalty. The 3rd Earl of Ormond purchased Kilkenny Castle in c. 1392. Cahir Castle passed to his illegitimate son James Gallda Butler. James Gallda was loyal to his mother’s family, the Desmonds, who were rivals to his father’s family, the Butlers.
In their book The Tipperary Gentry, William Hayes and Art Kavanagh tell us that the rivalry between the Butlers of Ormond and the Fitzgeralds of Desmond turned to enmity when the War of the Roses broke out in England, with the Ormonds supporting the House of Lancaster and the Desmonds the House of York. The enmity found expression in the battle at Pilltown in 1462. The enmity continued for over a century, and the last private battle between the Ormonds and the Desmonds was the Battle of Affane, County Waterford, in 1565. 
Thomas Butler (d. 1558) was created the 1st Baron Caher (of the second creation), County Tipperary, in 1543. He married Eleanor Butler, daughter of Piers Butler 8th Earl of Ormond (d. 26 August 1539) and Margaret Fitzgerald, daughter of Gerald FitzGerald, 8th Earl of Kildare (d. 3 September 1513). Their son Edmund became the 2nd Baron Caher (died 1560) but the title died with him and The Peerage website tells us his barony fell into abeyance between his two aunts.
The brother of Thomas 1st Baron Caher, Piers Butler (d. after February 1567/68) had a son Theobald who was then created 1st Baron Caher [Ireland, of the 3rd creation] on 6 May 1583. (see The Peerage website )
It was Piers Rua Butler, the 8th Earl of Ormond (c. 1467 – 1539), who brought peace between the warring factions of Fitzgeralds of Desmond and the Butlers of Ormond. He married Margaret Fitzgerald, daughter of Gerald (or Garret) Fitzgerald (1455-1513) 8th Earl of Kildare. His efforts culminated in a treaty called the Composition of Clonmel. It stated that Edmund Butler of Cahir should receive the manor of Cahir on condition that he and all his heirs “shall be in all things faithful to the Earl [of Ormond] and his heirs.” The Barons of Cahir were not allowed to keep their own private army nor to exact forced labour for the building or repair of their castle or houses. (see ).
This storyboard tells us that Ireland was dramatically different from Renaissance England in its language, customs, religion, costume and law. It was divided into 90 or so individual “lordships” of which about 60 were ruled by independent Gaelic chieftains. The rest were ruled by Anglo-Irish lords. Queen Elizabeth saw Ireland as a source of much-needed revenue. She did not have sufficient resources nor a strong enough army to conquer Ireland so she encouraged her authorities in Dublin to form alliances between the crown and any local chieftains who would submit to her authority. Many chieftains who submitted did so in order to assist them in their own power struggles against their neighbours. Elizabeth especially needed this support in order to ensure that if Spain invaded Ireland she would be able to quell rebellion.
Walter Devereux, 1st Earl of Essex, travelled to Ireland to subjugate Ulster and Shane O’Neill (“The O’Neill) in 1573. He failed, and had to sell of much of his land in England to pay debts accrued from raising an army. He died in Dublin of typhoid in 1576.
His son, the 2nd Earl of Essex came to Ireland to quell a rebellion which included the rise of Hugh O’Neill, 2nd Earl of Tyrone (1550-1616), cousin of Shane O’Neill.
The storyboard tells us that Hugh O’Neill fought alongside the 1st Earl of Essex in Ulster between 1573 and 1575. He also fought for Queen Elizabeth in 1580 against the rebel Gerald Fitzgerald, 14th Earl of Desmond (circa 1533, d. 11 November 1583), and as thanks he was made Earl of Tyrone. However, he turned against the crown in 1594 and formed an alliance with Red Hugh O’Donnell to fight against the Queen’s troops, in the Nine Years War.
The ties between the Earls of Essex and Queen Elizabeth I are complicated. When Walter Devereux the 1st Earl died in Ireland, his wife, Lettice Knollys, remarried. She and Queen Elizabeth’s favourite, Robert Dudley Earl of Leicester, married secretly, a fact which enraged the disappointed Queen. It was Robert Dudley who introduced his stepson Robert Devereux 2nd Earl of Essex to Elizabeth and he subsequently became her favourite, alongside Walter Raleigh. However, Elizabeth was to be angered again when this next favourite, Devereux, also secretly married, this time to Frances Walsingham, who was the widow of Sir Philip Sidney. We came across her before when we visited Portumna Castle as she later married Richard Bourke 4th Earl of Clanricarde. Philip Sidney was the son of Henry Sidney (or Sydney) who had been Lord Deputy of Ireland.
Robert Devereux the 2nd Earl of Essex sought to re-win courtly favour by going to fight in Ireland, following the footsteps of his father, and persuaded Elizabeth to name him Lord Lieutenant of Ireland.
In May 1599, Essex and his troops besieged Cahir Castle. He arrived with around two to three thousand men, a cannon and a culverin, a smaller and more accurate piece of heavy artillery.
Thomas Butler the 10th Earl of Ormond, who owned the castle in Carrick-on-Suir and was another favourite of the Queen, as he had grown up with her in the English court. However, the storyboards tell us that he at first rebelled, alongside Thomas Butler 2nd Baron Cahir (or Caher – they seem to be spelled interchangeably in historical records) and Edmond Butler, 2nd Viscount Mountgarret (1540-1602), another titled branch of the Butler family.
By the time of the 1599 siege, the Earl of Ormond was fighting alongside Essex, and Cahir Castle was held by rebels, including Thomas Butler’s brother James Gallada Butler (not to be confused with the earlier James Galda Butler who died in 1434). Thomas Butler 2nd Baron Cahir travelled with Essex toward the castle. Baron Cahir sent messengers to ask his brother to surrender the castle but the rebels refused. Thomas Butler 2nd Baron Cahir was suspected of being involved with the rebels. Thomas was convicted of treason but received a full pardon in 1601 and occupied Cahir Castle until his death in 1627. James Gallada Butler claimed that he had been forced by the rebels to fight against Essex. Essex and his men managed to capture the castle.
During the three days of the siege, the castle incurred little damage, mostly because the larger cannot broke down on the first day! Eighty of the defenders of the castle were killed, but James Gallada Butler and a few others escaped by swimming under the water mill. This siege was to be the only time that castle was taken by force. James Gallada recaptured the castle the following year and held it for some months. The Butlers regained possession of the castle in 1601.
Inside the castle in one room was a wonderful diorama of this siege of Cahir Castle, with terrifically informative information boards.
Failing to win in his battles in Ireland, however, Essex made an unauthorised truce with Hugh O’Neill. This made him a traitor. The Queen did not accept the truce and forbid Essex from returning from Ireland. He summoned the Irish Council in September 1599, put the Earl of Ormond in command of the army, and went to England. He tried to raise followers to oust his enemies at Elizabeth’s court but in doing so, he brought a small army to court and was found guilty of treason and executed.
Cahir Castle was taken again, this time by Murrough O’Brien (1614-1674, 6th Baron Inchiquin and later created 1st Earl of Inchiquin in 1647) in the Confederate War, which followed the rebellion of 1641. O’Brien fought on the side of the Crown – his ancestor Murrough O’Brien was created 1st Baron Inchiquin in 1543 by the Crown in return for converting to Protestantism and pledging allegiance to the King (Henry VIII). Since he took the castle for the crown, it implies that at this time Lord Caher fought against the crown again – and since the information boards tell us that the 1599 siege was the only time it was taken by force, force must not have beeen used at this later time. This must have been the time that Oliver Cromwell in 1650, when the occupants surrendered peacefully.
Once invaders get through the portcullis they are trapped in a small area, where defenders can fire arrows and stones at them. The walls of this area slope outwards towards the bottom, known as a base batter, so falling rocks bounce off them to hit the invaders.
The Butlers of Ormond also had to forfeit their land in the time of Oliver Cromwell’s Protectorate. Both branches of the Butlers had their lands restored with the restoration of the monarchy with Charles II in 1662.
The castle layout was changed considerably and enlarged during work to repair some of the damage caused by the battles, but was then left abandoned until 1840 when the partial rebuilding of the Great Hall took place. 
The core of the castle is the keep.
There’s an excellent history of Cahir on the Cahir Social and Historical Website:
“Throughout the reigns of Elizabeth I and Charles I, Cahir Castle appears as a frequent and important scene in the melancholy drama of which Ireland was a stage. The Castle was taken and re-taken, but rarely damaged and through it all remained in the hands of the Roman Catholic Butlers of Cahir. By this time Cahir had become a great centre of learning for poets and musicians. Theobald, Lord Cahir [I assume this was 1st Baron Cahir of second creation who died in 1596] was said by the Four Masters “to be a man of great benevolence and bounty, with the greatest collection of poems of any of the Normans in Ireland”.
“A study of the Butler Family in Cahir in the sixteenth and seventeenth centuries reveals the rise and fall of one of the minor branches of the House of Ormond. At the end of the fifteenth century, they possessed extensive powers, good territorial possessions and a tenuous link with the main branch of the Butler family. During the sixteenth century, their possession was strengthened by the grant of the title of Baron of Cahir with subsequent further acquisition of land, but they came under closer central government control. A complete reversal in their relations with the Earls of Ormond occurred, strengthened by various marriage alliances. They also participated in political action, both in the Liberty of Tipperary and at National Level. In the late sixteenth and early seventeenth centuries their position was affected by their adherence to Roman Catholicism, which resulted in their revolt during the Nine Years War, and subsequent exclusion from power by the Central Administration. They formed part of the Old English Group and as such, suffered from the discriminatory politics practiced by the Government. From 1641 they became minor landowners keeping their lands by virtue of the favour of their relative, the Duke of Ormond. In 1647 the Castle was surrendered to Lord Inchiquin for Parliament but re-taken in 1650 by Cromwell himself, whose letter describing acceptable terms of surrender still survives. At the restoration of Charles II, in 1660, George Matthews, (as Warden of Cahir Castle and half-brother to the Duke of Ormond), retained the Cahir lands for the Lord Cahir, then a minor.”  George Matthew (or “Mathew,”1645-1735) was married to Eleanor Butler, daughter of Edmond Butler, 3rd/13th Baron Dunboyne. She seems to have married twice: first to Edmond Butler son of 3rd Baron Cahir, then to to George Matthew. Her son was Piers Butler, 4th Baron Cahir, who was just seven when his father died.
Piers Butler 4th Baron Cahir (1641-1676) married George Mathew’s niece, Elizabeth Mathew (1647-1704). They had no male issue, but two daughters. His daughter Margaret married Theobald Butler, 5th Baron Cahir (d. 1700), great-grandson of the 1st Baron Cahir.
“Despite embracing the Jacobite Cause in the Williamite Wars, the Cahir estate remained relatively intact. However, the Butlers never again lived at Cahir Castle but rather at their country manor, Rehill House, where they lived in peace and seclusion from the mid-seventeenth century, when not living abroad in England and France.
…By 1700 a sizeable town had grown around the Castle, although hardly any other buildings survive from this period. Agriculture, milling and a wide range of trades would have brought quite a bustle to the muddy precursors of our present streets. At this time, the Castle was quite dilapidated and was let to the Quaker William Fennell, who resided and kept a number of wool combers at work there.” 
Margaret Butler daughter of the 4th Baron Cahir was the 5th Baron Cahir’s second wife. His first wife, Mary Everard, gave birth to his heir, Thomas (1680-1744), 6th Baron Cahir. Thomas had several sons, who became 7th (d. 1786) and 8th Barons Cahir (d. 1788), but they did not have children, so that title went to a cousin, James Butler (d. 1788), who became 9th Baron Cahir.
“On the completion of Cahir House [in the town, now Cahir House Hotel] in the later 1770’s, Fennell rented Rehill House from Lord Cahir and lived there over half a century. [The Barons moved to Cahir House.] A strong Roman Catholic middle class emerged. James, 9th Lord Cahir [d. 1788], practiced his religion openly. He maintained strong links with Jacobite France, and paid regular visits to England. While not a permanent resident, he kept his Cahir Estates in impeccable order and was largely responsible for the general layout of the Town of Cahir. Under his patronage, some of the more prominent buildings such as Cahir House, the Market House and the Inn were built during the late 1770s and early 1780s. In addition, the Quakers built the Manor Mills on the Bridge of Cahir, the Suir Mills (Cahir Bakery), and the Cahir Abbey Mills in the period 1775-90.“
The son of the 9th Baron Cahir, Richard, became 10th Baron and 1st Earl of Glengall.
“… The young Lord Cahir married Miss Emily Jeffereys of Blarney Castle and together they led Cahir through the most colourful period of its development…Richard, Lord Cahir, sat in The House of Lords as one of the Irish Representative Peers, and in 1816 was created Earl of Glengall, a title he enjoyed for just 3 years. He died at Cahir House of typhus in January 1819, at the age of 43 years. Richard, Viscount Caher, (now 2nd Earl of Glengall), had already taken his place in political circles while his mother, Emily, ran the Estate with an iron fist.” 
“During the Great Famine (1846-51), Lord and Lady Glengall did much for the relief of the poor and the starving. Lord Glengall’s town improvement plan was shelved in 1847 due to a resulting lack of funds and his wife’s fortune being tied up in a Trust Fund. The Cahir Estates were sold in 1853, the largest portion being purchased by the Trustees of Lady Glengall. This sale came about due to Lord Glengall being declared bankrupt. The Grubbs had by now become the most important Quaker family in the district and bought parts of the Cahir Estate during the 1853 sale...
In the interim, Lady Margaret Butler (elder daughter and heir of Lord Glengall) had married Lieut. Col. Hon. Richard Charteris, 2nd son of the 9th Earl of Wemyss & March. Using a combination of her mother’s Trust and Charteris funds, Cahir Town and Kilcommon Demesne were repurchased.
Lady Margaret, although an absentee landlord, resident in London, kept a close watch on her Cahir Estates through two excellent managers, Major Hutchinson and his successor William Rochfort… Her son, Richard Butler Charteris took over her role in 1915 and remained resident in Cahir from 1916 until his death in 1961. In 1962, the House, and circa 750 acre estate core (within the walls of Cahir Park and Kilcommon Demesne) were auctioned…And so ended the direct line of Butler ownership in Cahir, almost 600 years.“ 
The castle became the property of the state after the death of Lord Cahir in 1961; it was classified as a national monument and taken into the care of the Office of Public Works. (see )
Our tour guide took us through the outside of the castle, showing us its defenses. Our tour ended inside the Great Hall, or dining hall.
The dining hall has a magnificent ceiling. The building would have originally been of two storeys, and taller. The appearance today owes much to restoratation work carried out by William Tinsley in 1840, when the building was converted into a private chapel for the Butler family. The hammer-beam roof and the south and east wall belong to this period. The external wall dates from the 13th century.
Next we explore the keep building.
2. Famine Warhouse 1848, Ballingarry, County Tipperary:
General information: 087 908 9972, email@example.com
From the OPW website https://heritageireland.ie/visit/places-to-visit/famine-warhouse-1848/:
“How did an ordinary farmhouse near Ballingarry, County Tipperary, become the site of a bloody siege and a monument of the Young Irelander Rebellion of 1848?
It was here that rebels, under the leadership of Protestant aristocrat William Smith O’Brien, besieged 47 police officers who had barricaded themselves into the McCormack homestead, taking 5 children hostage. After two of their number were killed, the rebels finally gave in. They were later transported to penal colonies abroad.
The Warhouse, as it became known, is now a museum. Its contents illuminate the history of the Young Irelander Rebellion, the trials of its leaders, their exile in Australia and escape to the USA. The exhibition places the rebellion in the context of the Great Famine and the upheaval that rocked Europe during that turbulent year.“
Traditionally it was known as Ballingarry Warhouse or The Widow McCormack’s House.
3. Holycross Abbey, County Tipperary:
From the OPW website https://heritageireland.ie/visit/places-to-visit/holycross-abbey/:
“As destination for pilgrims, Holy Cross Abbey, near Thurles, County Tipperary, has a rich history. Pilgrims travelled here for eight centuries to venerate the relic after which the abbey and surrounding villages are named – a piece of the True Cross of Christ’s crucifixion.
Today this working parish church is a peaceful landmark and a place for quiet contemplation and historical discovery. As well as inspecting the relic of the cross, you can marvel at the building’s ornate stonework. The chancel is possibly the finest piece of fifteenth-century architecture in the country. The abbey also houses one of the only surviving medieval wall paintings in Ireland.“
4. The Main Guard, Sarsfield Street, Clonmel, County Tipperary:
General Information: 052 612 7484, firstname.lastname@example.org
From the OPW website https://heritageireland.ie/visit/places-to-visit/the-main-guard/:
“In the seventeenth century County Tipperary was a palatinate, ruled by James Butler, duke of Ormond. When the duke decided he needed a new courthouse, he built one in the heart of Clonmel [built in 1673]. Later, when it was used as a barracks, it became known as the Main Guard.
A fine two-storey symmetrical building, some elements of its design were based on works by the famous Sir Christopher Wren.
In the eighteenth century it was the venue for the Clonmel Assizes. The most notable trial it witnessed was that of Father Nicholas Sheehy, the anti-Penal Laws agitator. Sheehy was hanged, drawn and quartered.
In about 1810, the ground floor was converted into shops, but the building has recently undergone an award-winning restoration. The open arcade of sandstone columns is once again an attractive feature of the streetscape, while inside you will find a fantastic exhibition and event space.“
5. Nenagh Castle, County Tipperary
General information: 067 33850, email@example.com
The OPW doesn’t seem to have a site for this currently, but there is information at a site about Nenagh:
“Nenagh Castle was built by Theobald Walter (the first of the Butlers of Ormond) around 1200. To this day the cylindrical keep adorns the town and like most keeps it formed part of the perimeter of the fortress. The walls have now almost disappeared, but fragments remain.
Built from limestone Nenagh Castle measures fifty-five feet in external diameter at the base and rises to a height of one hundred feet. The Castle features four storeys and thanks to a recent renovation this wonderful landmark now represents the town’s premier tourist attraction.
The building and has stone spiral stairs to the top. There are 101 steps in all to the top. Access to the tower is through a passageway within the base of the wall. This has low head room and visitors will need to stoop to avoid hitting the stone above. All children under the age of 18 must be accompanied by an adult. 
6. Ormond Castle, Carrick-on-Suir, County Tipperary:
General Information: 051 640787, firstname.lastname@example.org
From the OPW website https://heritageireland.ie/visit/places-to-visit/ormond-castle/:
“Joined on to an earlier medieval riverside castle, Ormond Castle Carrick-on-Suir is the finest example of an Elizabethan manor house in Ireland. Thomas, 10th Earl of Ormond [“Black Tom” (1531-1614)], built it in 1565 in honour of his distant cousin Queen Elizabeth.
The magnificent great hall, which stretches almost the whole length of the building is decorated with some of the finest stucco plasterwork in the country. The plasterwork features portraits of Queen Elizabeth and her brother Edward VI and many motifs and emblems associated with the Tudor monarchy.“
The castle has a low and wide-spreading addition to an older castle, which consisted of two massive towers set rather close together. The castle is joined to these towers by a return at each side, making an enclosed courtyard. The facade is of two storeys with three gables and a central porch and oriel. It is only one room thick. It is virtually unfortified, having no basement, and windows only three freet from the ground, and a few shot-holes for defence by hand-guns, Craig points out. The windows on the ground floor may have been widened at some point.
Mark Bence-Jones writes:
“The house, which is horseshoe shaped, forming three sides of a small inner court, and the castle the fourth. The house is of 2 storeys with a gabled attic; the towers of the castle rise behind it. The gables are steep, and have finials; there are more finials on little piers of the corners of the building. There are full-sized mullioned windows on the ground floor as well as on the floor above, the lights having the slightly curved heads which were fashionable in late C16. There is a rectangular porch-oriel in the centre of the front, and an oriel of similar form at one end of the left-hand side elevation. The finest room in the house is a long gallery on the first floor, which had two elaborately carved stone chimneypieces – one of which was removed to Kilkenny Castle 1909, but has since been returned – and a ceiling and frieze of Elizabethan plasterwork. The decoration includes busts of Elizabeth I, who was a cousin of “Black Thomas,” Ormonde through her mother, Anne Boleyn, and used to call him her “Black Husband”: she is said to have promised to honour Carrick with a visit. The old castle served as part of the house and not merely as a defensive adjunct to it: containing, among other rooms, a chapel with carved stone angels.” 
Thomas Butler (1582-1614) the 10th Earl of Ormond is a fascinating character. He was the eldest son of James Butler, 9th Earl of Ormond, and his wife Joan Fitzgerald, daughter of the 10th Earl of Desmond. Because he was dark-haired, he was known to his contemporaries as “Black Tom”or “Tomas Dubh”. As a young boy, Thomas was fostered with Rory O’More, son of the lord of Laois (his mother was granddaughter of Piers Rua Butler, 8th Earl of Ormond) before being sent to London to be educated with the future Edward VI. He was the first member of the Butler family to be brought up in the protestant faith. In 1546, he inherited the Ormond earldom following the sudden death of his father. He fought against the Fitzgerald Earls of Desmond in the Desmond Rebellions, as he was loyal to the British monarchy. He was made Lord Treasurer of Ireland and a Knight of the Garter.
He was highly regarded by Queen Elizabeth to whom he was related through her mother Anne Boleyn. Anne Boleyn was the granddaughter of the 7th Earl of Ormond making Elizabeth and Thomas cousins. Thomas married three times but left no heir and was succeeded by his nephew Walter Butler 11th Earl of Ormond. He died in 1614 and was buried in St Canice’s cathedral, Kilkenny.
James Butler the 12th Earl of Ormond and 1st Duke of Ormond (1610-1688) spent much of his time here and was the last of the family to reside at the castle. On his death in 1688 the family abandoned the property and it was only handed over to the government in 1947, who then became responsible for its restoration.
7. Rock of Cashel, County Tipperary:
General Information: 062 61437, email@example.com
From the OPW website https://heritageireland.ie/visit/places-to-visit/rock-of-cashel/:
“Set on a dramatic outcrop of limestone in the Golden Vale, the Rock of Cashel, iconic in its historic significance, possesses the most impressive cluster of medieval buildings in Ireland. Among the monuments to be found there is a round tower, a high cross, a Romanesque chapel, a Gothic cathedral, an abbey, the Hall of the Vicars Choral and a fifteenth-century Tower House.
Originally the seat of the kings of Munster, according to legend St. Patrick himself came here to convert King Aenghus to Christianity. Brian Boru was crowned High King at Cashel in 978 and made it his capital.
In 1101 the site was granted to the church and Cashel swiftly rose to prominence as one of the most significant centres of ecclesiastical power in the country.
The surviving buildings are remarkable. Cormac’s Chapel, for example, contains the only surviving Romanesque frescoes in Ireland.“
8. Roscrea Castle and Damer House, County Tipperary:
General information: 0505 21850, firstname.lastname@example.org
From the OPW website https://heritageireland.ie/visit/places-to-visit/roscrea-heritage-centre-roscrea-castle-and-damer-house/:
“In the heart of Roscrea in County Tipperary, one of the oldest towns in Ireland, you will find a magnificent stone motte castle dating from the 1280s. It was used as a barracks from 1798, housing 350 soldiers, and later served as a school, a library and even a sanatorium.
Sharing the castle grounds is Damer House, named for local merchant John Damer, who came into possession of the castle in the eighteenth century. The house is a handsome example of pre-Palladian architecture. It has nine beautiful bay windows. One of the rooms has been furnished in period style.
The grounds also include an impressive garden with a fountain, which makes Roscrea Castle a very pleasant destination for a day out. There is also a restored mill displaying St Crónán’s high cross and pillar stone.“
This was originally the site of a motte and bailey fortification known as King John’s Castle. The original wooden castle was destroyed in the late 13th century and was replaced with a stone structure built in 1274-1295 by John de Lydyard. The castle was originally surrounded by a river to the east and a moat on the other sides.  It was granted to the Butlers of Ormond in 1315 who held it until the early 18th Century. The castle as we see it today was built from 1332.
Eoin Roe O’Neill, at the head of 1,200 men, stormed Roscrea in 1646 and reportedly killed every man, woman and child. The only survivor was the governor’s wife, Lady Mary Hamilton (1605-1680), who was a sister to the Earl of Ormond [married to George Hamilton, 1st Baronet of Donalong County Tyrone and of Nenagh, County Tipperary]. She was again forced to play host in the castle to O’Neill three years later which again ended by the guests looting everything in sight. 
Damer House is of three storeys and nine bays and has a scroll pediment doorway and inside, a magnificent carved staircase. The Irish Georgian Society was involved in saving it from demolition in the 1960s.
Roscrea Castle was sold to the Royal Hospital, Kilmainham, by the James Butler, 2nd Duke of Ormond in 1703. It was bought by Joseph and his nephew John Damer (1674-1768) in 1722. The Damer family who built an elegant three-storey pre-Palladian house in the courtyard in c. 1730.
In their book The Tipperary Gentry, Hayes and Kavanagh tell us that Joseph Damer was born in Dorset in England in 1630. The came to Ireland after the restoration of Charles II when land was being sold cheaply by Cromwellian soldiers who were given land instead of pay but did not want to remain in Ireland. He bought land in Tipperary and became a sheep farmer. He also became involved in banking in Dublin. His nephew John acted as his agent in Tipperary. Jonathan Swift wrote a ditty mocking Joseph Damer’s parsimony:
“He walked the streets and wore a threadbare cloak
He dined and supped at charge of other folk
And – by his look – had he held out his palms
He might be thought an object fit for alms.”
He had no children and left his vast fortune when he died in 1720 to his nephews John (1674-1768) and Joseph (1676-1736), sons of his brother George Damer. He was so wealthy that he entered folklore with tales of how he gained his wealth, and he was compared to King Midas, as if everything he touched turned to gold.
The nephew John had no children and his brother Joseph inherited. Joseph became MP for Tipperary in 1735. He died three years later.
Robert O’Byrne tells us that his son Joseph (1717-1798) inherited the house and castle was later created the Earl of Dorchester.  He was an absentee landlord and his brother managed his Irish properties. He built a mansion named Damerville which was very grand, but was demolished in 1775. Their sister Mary married William Henry Dawson, 1st Viscount Carlow, who lived at Emo in Laois. It was her offspring who later inherited the Damer properties.
Joseph’s son John (1744-1776) married Ann Seymour, a sculptress. He spent all of his inheritance and killed himself. Subsequently it was his younger brother George who inherited the title to become 2nd Earl of Dorchester. None of Joseph’s offspring had children, however, so the properties passed to the 2nd Earl of Portarlington, a second cousin, who assumed the name Dawson-Damer.
Mary who had married the 1st Viscount Carlow had a son John Dawson (1744-1798) who became 1st Earl of Portarlington, Queen’s County. He married Caroline Stuart, daughter of the 3rd Earl of Bute and his writer wife, Mary Wortley Montagu. He commissioned James Gandon to built Emo Court in Queen’s County (Laois). It was his son John Dawson (1781-1845), 2nd Earl of Portarlington, who inherited the Damer fortune and lands, and added Damer to his surname.
The castle was used as a barracks from 1798, housing 350 soldiers. It was used later as a school, a library, and a tuberculosis sanatorium. Roscrea Castle fell into disrepair in the 19th century, and when the roof collapsed extensive repairs were needed in the 1850s. It was named a national monument in 1892, and is now under the care of the OPW.
9. Swiss Cottage, Ardfinnan Road, Cahir, County Tipperary:
General Information: 052 744 1144, email@example.com
From the OPW website https://heritageireland.ie/visit/places-to-visit/swiss-cottage/:
“The Swiss Cottage, just outside the heritage town of Cahir, is a cottage orné – a fanciful realisation of an idealised countryside cottage used for picnics, small soirees and fishing and hunting parties and was also a peaceful retreat for those who lived in the nearby big house.
Built in the early 1800s [around 1810] by Richard Butler, 1st Earl of Glengall, who, we believe, managed to persuade world-famous Regency architect John Nash to design it [he also designed Buckingham Palace for the Crown]. Originally, simply known as “The Cottage” it appears to have acquired its present name because it was thought to resemble an Alpine cottage.
Inside, there is a graceful spiral staircase and some exquisitely decorated rooms. The wallpaper is partly original and partly the fruit of a 1980s restoration project, in which the renowned fashion designer Sybil Connolly was responsible for the interiors.“
We visited the Swiss Cottage in June 2022. The guide told us that the Glengalls probably never even spent a night in their cottage! They used it for entertaining. A Swiss Cottage, or cottage ornee, was the ultimate in impressive entertainment. It was meant to look like it had grown from the ground, and it was designed deliberately off-kilter and asymmetrical with different windows, wavy rooves, oddly shaped rooms. Even the expensive floorboards were painted to look like they were made of a cheaper wood!
The National Inventory describes it:
“The building, constructed as an architectural toy, was used as a lodge for entertainment purposes and was designed specifically to blend with nature. The roof pitches and tosses and varies in length while differing window sizes and openings punctuate it. The verandah and balconies, although luxury features, have been fashioned to appear humble with exposed rustic tree trunk pillars. The asymmetrical design of the cottage, although immediately apparent of architectural detailing, is deliberately flawed and distorted to appear unsophisticated. Both the building and its setting right down to its cast-iron rustic fencing maintains a sense of blending with nature as it was originally designed.” 
Unfortunately we were not allowed to take photographs inside. I took a few photographs looking through the windows. You can see better photographs of the interior on the OPW website.
Downstairs has a room off either side of the hallway, the Dufour Room and the Music Room. The Dufour room is so called due to some original Dufour wallpaper, depicting Constantinople, much of which has been reproduced to line the room. Dufour was one of the first Parisian manufacturers creating commercially produced wallpaper. Another door from the central hall leads to a limestone stairway and basement. The first floor interior comprises a landing with rooms leading directly to the west (Small bedroom) and east (Master bedroom) through angular-headed timber panelled doors.
Every window has a different shape.
Walking under the balcony one is embraced with the glorious scent of the roses and other flowers.
