Clonalis House is arguably the finest expression of the Victorian-Italianate style in County Roscommon.

Stephen and I were invited to join friends for a weekend in County Westmeath and took the opportunity to visit Clonalis House in County Roscommon. We were particularly eager to visit the house once Stephen heard that it is the house belonging to the O’Conor Dons. The O’Conor Dons are descended from the last High Kings of Ireland. Stephen knew the last High King of Ireland, Father Charles O’Conor, at school, as a gentle elderly priest sweeping leaves in Clongowes Wood College. Stephen has affectionate memories of him, and was impressed by his humility and contentedness. Unfortunately since Father Charles became a Catholic priest, the line died out. The house was bequeathed to Father Charles’s sister, Gertrude, who married Richard Rupert Nash, and passed then to her son Pyers, who added the name O’Conor to his last name Nash. The term “Don” refers originally to hair colour, and there was another branch of the O’Conor family called “Rua” or red, but the line has died out. However, the term “O’Conor Don” is a title, applying to the Chieftain of the O’Conors of Connacht.

We were running late as I find Google always underestimates the time it will take to any destination over an hour away, so we arrived just in time for the last house tour at 4pm. I took the wrong turn as we drove up the long entrance driveway, turning off to the self-catering holiday homes in a former courtyard, by mistake. I was in such a rush that I didn’t notice the beauty of the drive up to the house, which I stopped to appreciate on the way out. The drive is one third of a mile long, stretching through parkland.

We had contacted the O’Conor Nashes in advance, and a young historian who now gives tours of the house welcomed us. She has a lot of facts to learn! The house is bursting with history. The family, impressively, can date their genealogical tree back to 1100 BC; there is a book detailing their pedigree in the library, signed and legitimised by Sir William Betham, Ulster King of Arms, in 1825. There is also a chart in the library listing the male line, which goes back to 75AD. The family produced 11 high kings of Ireland and 24 kings of Connacht. [1]

Our guide began the tour outside. She pointed out a large stone in front of the house. It was brought from Rathcroghan in County Roscommon, about nine miles from the house. Upon this stone, called the Coronation Stone, the High Kings of Ireland were crowned.

There is an indentation like a footprint on the top of the stone, and this is supposed to be where each king put a foot during his coronation. According to Mrs. Pyers O’Conor-Nash’s entry in Sybol Connolly’s book, In An Irish House, published by Weidenfeld and Nicolson in London in 1988, one of the last to be crowned king of Connacht was Felim O’Conor, who was killed in the battle of Athenry when fighting against his Connacht neighbours the de Burghs and the de Berminghams in 1316.

The Clonalis website describes the ceremony of inauguration of a king. He symbolically married the soil over which he was to rule, and the sacred stone acted as the King’s bride in the ceremony known as “Banais Ri” (the King’s Marriage”). This stone was probably used to inaugurate thirty O’Conor kings!

I was impressed immediately by the symbol on the house of the arm holding the sword:

Randall MacDonnell tells us in his book The Lost Houses of Ireland that in 1175 Roderick O’Conor, the High King of Ireland, agreed to the following: “Henry [King Henry II of England] grants to Roderick, his liege King of Connacht, as long as he faithfully serves him, that he shall be King under him…and as his man.” This agreement is known to history as the Treaty of Windsor, which St. Laurence O’Toole had negotiated on behalf of the Irish High King. Sadly, Roderick’s own sons plotted against him so, in 1187, he abdicated and spent the remainder of his life as a religious in the Abbey of Cong in the west of Ireland. According to the website, at the height of O’Conor\O’Connor power, as High Kings of Ireland in the 12th century, Tuam and Dunmore in Galway were their Ecclesiastic and Administrative centres. O’Conor castles from the 14th century can be found in Ballintubber, County Roscommon, and in Roscommon town, and the one is Ballintubber is still owned by the family, although they have not resided there since the seventeenth century.

Possession of the lands can be traced back to the O’Conor Dons for over 1,500 years. The original house was built in the late seventeenth century, and incorporated a medieval castle, but it flooded regularly due to its position by the River Suck, so a new house was built by Charles Owen O’Conor Don and the family moved in 1880 to the present house. The old house is now a ruin and can be seen from the driveway. On the official website, the current resident, Pyers O’Conor Nash (his mother Gertrude married a Nash, after being born an O’Conor), writes touchingly that Charles Owen built the new house also because the old house made him too sad, as he lost his parents when living there, at the age of seven, and then at the age of 27, lost his wife Georgina.

The River Suck. We passed this on the way out (and in, when I was driving too carefully to notice!). What a romantic spot!

The current house is two storeys over basement with a dormered attic. It was designed by a young popular English architect Frederick Pepys Cockerell. It is a mixture of Queen Anne Revival and Victorian Italianate style. Frederick Pepys Cockerell had spent time studying architecture in Italy, and was attempting to establish a practice in Ireland (he also built Blessingbourne in County Tyrone for the Montgomery family) [2]. It has a rendering of cement and is one of the first concrete houses constructed in Ireland [3]. Cockerell died shortly after building work at Clonalis began in 1879.

The Italianate feature is the central projecting tower, containing the main entrance in a balustraded porch, and a pyramidal roof. The front double-leaf door inside the porch is timber-panelled and glazed, and is flanked in the porch by sidelights. The porch has Doric pilasters, and Ionic pilasters on the storey above. Mark Bence-Jones, in his Irish Country Houses, points out the scroll-pediments over the windows on the ground floor, some set in round-headed recesses. [4]

The high-pitched roof is carried on a cornice of elaborately moulded brackets. The chimneystacks are tall and wide: some of them are decorated with mouldings and recessed panels; others are pierced with arches. [see Bence-Jones]

You can see photographs of the interior of the house on the Clonalis website.

We entered the large Hall. To my untrained eye, the décor looked quite medieval. This is probably due to the large oak staircase beyond an archway, the fireplace, and the banner hanging over the stairs, which reminded me of the tattered banners than hang in St. Patrick’s Cathedral in Dublin. The banner, our guide explained, was carried by Denis O’Conor Don at the coronation of George V in 1911. Later we saw the military uniform which Denis wore to the coronation in a museum room in the house. Denis O’Conor Don was the first person to represent Irish Gaelic families at an English coronation. Our guide referred us to the Ionic columns of marble, explaining that the pink colour of the marble is unusual, and is from Mallow in County Cork. The ceiling of the hall has a modillion cornice and arches. [5]

We walked though the broad arched corridor which leads from one side of the hall to the main reception rooms: the Drawing Room, Dining Room and Library. Terence Reeves-Smyth describes:

The first of these to be entered is the large and rather charming drawing room, which has fine Boulle furniture and some beautifully modelled figures of Meissen, Limoges and Minton porcelain.

The room is bright and airy with large windows and lovely mirrors, and marble chimneypieces which were transferred by Cockerell from the old house. Reeves-Smyth continues:

In the library mahogany bookcases are over 5000 books, including the diaries of Charles O’Conor of Belnagare (1710-90), the great historian and antiquary.”

We were bowled over by the library, as is our tour guide, as she told us that she would not dare touch any of the books – and we are not allowed to either! We itched to, of course. I longed to see if the cream bound set of Jane Austen was a first edition. Bence-Jones writes that the bookcases are mahogany, designed by Pepys-Cockerell. Much of the library was collected by Charles O’Conor of Belnagare. We saw the genealogical pedigrees, and our guide used the portraits, mostly in the dining room, to tell us more about the history of the family. You can see great photographs of the library on the Irish Aesthete’s website. [6] The marble chimneypiece is flanked by niches for turf, and was also designed by Pepys-Cockerell.

I was interested to hear that one of the family, Hugh O’Conor, founded Tucson, Arizona! When I visit my sister in the U.S., I fly in to Tucson. Another ancestor, Major Owen of Ballintubber, lost his lands under Cromwell, regained them under Charles II and mortgaged them to raise troops for James II. The family were able to buy back some of the land but some was never recovered. Major Owen backed the wrong man, as indeed did my Baggot ancestors, being loyal to the Catholic James II rather than supporting William III, James’s son-in-law and nephew (Charles II arranged for his brother James’s daughter Mary to marry William III, to appease the Protestants, to prove that despite his brothers’ leaning toward Catholicism, he was raising his children to be good Protestants).

It was Parliament who invited William III to be King of England and to replace James II. Battles took place in Ireland as James II went to Ireland to raise troops. The Irish were loyal to the monarchy and not as many had converted to Protestantism, as in England or Scotland. William however brought troops from nearly a dozen countries. I hate to hear the bad names James has been called, and he was in fact an excellent military man as proven by his earlier leadership of the British navy. But ultimately William III was crowned king alongside his wife Mary, and Major Owen O’Conor lost his land!

The website tells us that the fortunes of the family were devastated and they were reduced to peasantry. It was Denis O’Conor (1674-1750) who recovered 600 acres of their former land, while living in a mud cottage in Kilmactranny in County Sligo. In 1820 the “Ballanagare” [there seems to be a variety of spellings of this townland] O’Conors, another branch of the family, succeeded to the O’Conor estates at Clonalis as the Clonalis branch became extinct in the male line.

The O’Conor family remained Catholic, and they have a Catholic chapel in the house. Our guide pointed out a chalice on the altar. It can be taken apart into three pieces, to be more easily hidden, as required during the time when Catholic priests were outlawed. The chalice belonged to Bishop Thaddeus O’Rourke, he consecrated it in 1722. He had to go into hiding and stayed with the O’Conor family. Many houses have secret “priest’s holes” where Catholic priests could hide. The altar in the chapel is called a penal altar as it was taken from the original house and dates to the time when masses had to be celebrated in secret. There is a photograph of the Father Charles whom Stephen knew in Clongowes, standing next to a cross in the National Museum. The cross was commisssioned by Turlough Mor O’Conor, who reigned from 1119 to 1156, so is nine hundred years old! It is called the Cross of Cong. Turlough Mor O’Conor was not just king of Connacht but High King of Ireland. See the website for more about this King and his cross. It bears the inscription, “A prayer for Turlough O’Conor, King of Erin, for whom this shrine was made.” [7] Turlough Mor founded a port in 1124 which was later developed into the city of Galway. He is buried in Clonmacnoise. [see 3].

The website has terrific accounts of the family history. You can read more about the Penal Laws and about Denis O’Conor, who regained the O’Conor property, which is now farmed by the O’Conor Nash family.

The house contains two museum-style rooms, displaying historical items from the family. One room displays letters and documents. The first president of Ireland, Douglas Hyde, was a neighbour, so there are letters from him. Charles Owen O’Conor (1838-1906), who joined the Irish Liberal Party and became MP for Roscommon, was President of the Society for the Preserving the Irish Language, a precursor to the Gaelic League. When he died, Douglas Hyde wrote of him: “It was owing to his foresighted statesmanship that the Irish language was originally placed by Parliament upon the curriculum of the Board of Intermediate Education and from that day until his death he never ceased… to champion its cause. Few men in Ireland know how much they owe to the watchful care of the O’Connor Don in this matter.” It was this Charles Owen who built the house in the 1870s. He also wrote the book, The O’Conors of Connacht.

One of the oldest documents is, according to Marguerite  O’Conor-Nash, “the last judgement handed down by the Brehon lawmakers.” Stephen and I puzzled over that, wondering who exactly determined Brehon laws, but that is research for another day! The day we visited, I was most excited to see the signature of King Louis XVI of France, the king who was beheaded, husband of Marie Antoinette. I was also excited to see a letter penned by the author (and surprisingly, cleric – surprising if you read his novel The Life and Opinions of Tristram Shandy, Gentleman, as it contains rather risque material!) Laurence Sterne. Reeves-Smyth also notes that there are pieces written by such famous personalities as O’Connell, Parnell, Gladstone, Trollope, Napper Tandy, and Samuel Johnson. It was a pity we were on the last tour of the day; I could see that Stephen longed to linger.

After Catholic Emancipation the O’Conor family played a pivotal role in Ireland’s history as Members of Parliament for County Roscommon, as one can see from the letters.

The other museum room had artefacts such as clothing and antiques, armour, etc. The family treasure their piece of history from the famous blind musician Turlough Carolan (1670-1738) whose memorial one can see in St. Patrick’s Cathedral in Dublin, who often played at Clonalis, and once remarked “When I am with the O’Connors, the harp has the old sound in it.”

The house is surrounded by formal lawns and terraces, with fine views over the park. We wanted to start our drive back to Westmeath before darkness, but took a few minutes to walk outside, and the beauty of the gardens enticed us to explore further.

The garden front has projecting ends, and a centre which breaks forward. Bence-Jones describes how the centre is crowned with a pedimented dormer gable and a balustraded balcony on very heavy console brackets. The side projections are also surmounted with balustrades and smaller dormer gables. In the centre is a doorcase with scrolled pediment. [8]

This is the view from the garden front of the house:

The stone wall at the side of the house had a great sculpture of a fox (or dog).

Then we walked further around, to the back of the house, down a path, past the sweeping view of parkland trees, into a wooded area leading into a splendid garden.

Past the sweep of magnificent trees:

The wooded area into which we could not help but be enticed:

The woods lead to a splendid garden.

We saw the signs for the “penal grave” and a bomb shelter, so couldn’t leave without seeing those!

The penal grave.

One of the residents of the house during World War I worried that the area would be bombed by a Zeppelin, and built the bomb shelter:

With sadness at leaving such a wonderful place, we slowly drove away up the driveway.

But we still couldn’t quite yet drag ourselves from the area. How could we leave without trying to find the intriguingly named location on our map, the “elephant’s grave”? We could see pillar in the near distance in a graveyard and wondered if that could be it, so abandoned the car to have a look. Unfortunately it was not the elephant’s grave and we didn’t find it, but we did come across the O’Conor graves. [9]

This is an impressive four storey sixteenth century tower-house ruin. We drove over to see it after visiting Harristown on Thursday 22nd August 2019, during Heritage Week.


Blackhall Castle was constructed by the Eustace family. The Eustaces of Castlemartin, County Kildare, nearby, were a branch of the “old English” FitzEustace  family who held the title of Baron Baltinglass. In the online introduction to an article published in 1955, “The Eustace Family & Their Lands in County Kildare,” by Major-General Sir-Eustace F. Tickell with additions by Ronald F. Eustice [Tickell’s article as published in the Journal of the County Kildare Archaeological Society Volume XI1I, No. 6 (1955)], Ronald Eustice describes the Eustace family’s importance in Irish history:

“[The story of the Eustace family] is a story closely linked with Irish history since the fourteenth century, the story of the birth of a great family and of its gradual disappearance from the County in the storms that have passed through Ireland during the last five-hundred years. 

“This was a family often divided against itself by deeply- held religious differences and by divergent political loyalties, a family whose important members so often chose the losing side: It was for a time perhaps the most powerful in Kildare (except of course the FitzGeralds), with lands scattered from Confey in the north to beyond the county boundary in the south; from the Dublin and Wicklow mountains in the east to Athy and Newbridge in the west. The triangle containing Naas, Ballymore Eustace and Old Kilcullen was almost one large family estate:

“Criche-Eustace  or  Cry-Eustace  it was called. Their castles, especially those at  Ballymore Eustace, Harristown, Castlemartin and Clongowes Wood, guarded the Pale for several centuries, and only fell at last to the guns of Ormonde and Cromwell. It was rare for a jury of county gentlemen to contain no Eustace, and on at least one occasion they formed a majority upon a panel of twelve… The family produced two Lords Deputy, three Lords Chancellor, two Lords Treasurer and the High Sheriff of Kildare on forty-five occasions. With a few notable exceptions they have now almost disappeared from Kildare, and their name has become a rare one in Ireland itself.” [1]


We drove up the wooded driveway to the castle, which has a later building attached, and is next to a beautiful old country house, now belonging to Jeffrey & Naomi White. The driveway passed the castle and entered a yard bordered by a fine stone wall. From here we were able to approach the back of the castle for a closer look.

The farmhouse next to the castle, itself probably built in the 1700s! And the stone wall, built with stones that were originally part of the castle.

We were greeted by a pair of dogs, and Naomi emerged from the house after them. She was very kind and welcoming, and after telling us a little about the ruin, invited us in to her house to tell us a bit more!

When Jeffrey and Naomi purchased the house, many years ago, the ruin still had its four walls. It was when they were away on a trip to Australia in 1999, leaving their property in the hands of a tenant who lived in the small cottage beside the ruin, that half of the castle came crashing to the ground. A severe storm caused a structural subsidence resulting in the complete collapse of the East section and parts of the North and South walls. [2] A deep loud rumble preceded the fall, and the dogs barked, as if they knew something momentous and disasterous was about to occur. Suddenly, nearly three sides of this huge ancient stone edifice tumbled to the ground, casting its giant rocks into the yard below. Fortunately nobody was injured and the cottage next door, sheltering the terrified tenant, remained unharmed, as did the centuries old farmhouse.
Naomi showed us pictures of the castle before the fall, as it stood when they first acquired the property – see the top photograph in Naomi’s collage:


The castle now existed as a one-sided shell next to an enormous heap of stones and rubble. Fortunately, when the Whites began to clear the rubble, they found the Sheelagh-na-Gig, the ancient fertility symbol which appears lewd to our modern eyes, intact. The figure had been inserted originally above the door frame of the castle. It has now been attached back on to the remains of the castle.


Naomi has an informative poster of Sheelagh-na-gigs in Britain and Ireland, which includes her Sheelagh-na-gig:


The remains of the castle have been made secure, which cost tens of thousands of euro, undertaken by the Whites with the help of a government grant. There is still much work to be done. Clearing the rubble was a massive task. The stone walls around the yard were built by an expert using some of the castle stones.


One can see where the floors of the castle were situated, the thickness of the walls, and the windows and fireplaces. I was particularly thrilled to see the intact round staircase, although we could not climb it, for safety reasons.


The Eustace family, according to Ronald Eustice, were a junior branch of the Le Poer family, whom I came across in my trip to Waterford, in Curraghmore (and mention of them in Salterbridge, in relation to Powerscourt, another Section 482 property). Four brothers Le Poer, of Norman origin, landed in Ireland with Henry II in 1171, and were granted lands in Ossory (Waterford). The stag with the crucifix between its antlers that tops Curraghmore is related to Saint Eustachius, a Roman centurion of the first century who converted to Christianity when he saw a miraculous stag with a crucifix between its antlers. This saint, Eustace, was probably the Patron Saint of the Le Poers since their family crest is the St. Eustace stag. I did not realise that St. Eustace is also the patron saint of Newbridge College in Kildare, where my father attended school and where for some time in the 1980s and 90s my family attended mass!

See the stag on the top of the crest on the top left, of this slip of paper I found in my father’s memorabilia from school.

The Eustace line of the Le Poer family are descended from Eustace le Poer, Baron of Kells and a Justice Itinerant in 1285. I’m familiar with the term “Justice Itinerant” as a Robert Bagod, whom I hope is my ancestor, also served in this position in 1274. It was a judge who had to travel to courts in various parts of the country. Robert Bagod ended up living in Limerick. According to the article, Eustace le Poer’s son Arnold took the name FitzEustace, which changed to Eustace soon after the introduction of surnames in 1465. [see 1] Ronald Eustice writes of the move of the Eustace ancestors into County Kildare:

By 1317, Arnold FitzEustace Le Poer certainly owned Castlemartin and the neighbouring townlands of Kilcullen, Brannockstown and Nicholastown, all just south of the Liffey. We also know that a FitzEustace was settled at Castlemartin before 1330; perhaps he was the Robert FitzEustace who was Lord Treasurer of Ireland in l 327. 

We can thus assume with a fair degree of certainty that the Eustace estates in County Kildare originated at least as early as the start of the fourteenth century, (they had been granted lands near Naas in 1355) and were based upon the family stronghold of Castlemartin at the great bend in the Liffey, and that this had been built by a member of a junior branch of the powerful Le Poer family from Waterford, who had been granted or had seized lands in Kildare. One of these FitzEustaces founded the Dominican Priory at Naas in 1356, with its church dedicated to St. Eustachius.”

Ronald Eustice continues:

“Calverstown was occupied by the Eustaces at a very early date when they built their Blackhall Castle south of the present village. … In 1484 and again in 1493, a Richard Eustace of Kilgowan (just east of Calverstown) was High Sheriff.

“Both Calverstown and Gormanstown were owned by the Viscounts Baltinglass, and Roland, later the 2nd Viscount, lived at the latter while his father was alive and occupying Harristown. At this time Calverstown was leased to a William Eustace, a juror in 1536. Both Calverstown (which contained “two castles prostrate”) and Gormanstown were forfeited after the Baltinglass rebellion, but Calverstown was re-granted to John ( [Eustace] son of William of Castlemartin), with Harristown and Rochestown, and this grant was confirmed to his son Maurice in l627.”


I like making the connection to Harristown, which we had visited earlier in the day!  Ron Eustice tells us that Sir Maurice Eustace gave Calverstown to his daughter Mary, either at the time of her marriage to Sir Richard Dixon, or upon his death. Calverstown passed to their son, Robert Dixon, later Colonel, and M.P. for Harristown from 1703-1713. On his death in 1725 it passed to his brother, Robert Dixon, and then to his sister Elizabeth, who had married Sir Kildare Borrowes, 3rd Bart. of Giltown, M.P. for Harristown in the Irish House of Commons in 1721. Their property, which would have included Blackhall Castle, had to be sold in 1747, however, to pay debts. Eustice notes that nothing remains of the occupation of Eustaces in either of their estates except Blackhall Castle. Wikipedia states that Sir Kildare Borrowes lived in Barretstown Castle, which could be why he was able to sell Blackhall. I’m not sure who owned (and perhaps occupied) Blackhall after that, before the Whites.
