[Rockfleet, but see Rossyvera entry] p. 243. “A two storey late-Georgian house on an inlet of Clew Bay close to an old castle of the celebrated C16 chieftain, Graunuaile or Grace O’Malley; enlarged and remodelled from 1939 onwards by the British diplomat, Sir Owen O’Malley, and Lady O’Malley (better known as the writer and traveller, Ann Bridge). An extra storey, with a flat roof, was added to the house; and a new two bay block built to the right of the original three bay front and projecting forwards from it. The new additions are of random ashlar with the joints raked out and well pointed to resist the weather; the windows are small Georgian sashes. The whole effect is that an old castle enlarged and modernised in C18. The principal rooms are arranged round an oval staircase hall, which is original to the house but was raised and surmounted by a lantern when the extra storey was added. One of the rooms is an octagon. The library bookcases and some of the chimneypieces are of macacauba, a Portuguese colonial timber, which Sir Owen, who was Ambassador in Lisbon, sent to Ireland in the form of containers for his furniture.”

Appraisal
A country house representing an important component of the early nineteenth-century domestic built heritage of County Mayo with the architectural value of the composition confirmed by such attributes as the deliberate alignment maximising on panoramic vistas overlooking Rockfleet Bay; the cruciform plan form centred on a restrained doorcase; the construction in a local fieldstone offset by “sparrow pecked” limestone dressings demonstrating good quality workmanship; and the uniform or near-uniform proportions of the openings on each floor with the principal “apartments” defined by a polygonal bow: meanwhile, aspects of the composition clearly illustrate the continued development or “improvement” of the country house in the twentieth century with ‘the whole effect [being] of an old castle enlarged and modernised in the eighteenth century’ (Bence-Jones 1978, 243). Having been well maintained, the elementary form and massing survive intact together with substantial quantities of the original fabric, both to the exterior and to the interior, thus upholding the character or integrity of the composition. Furthermore, an adjoining walled garden (extant 1897); and lengthy outbuildings (extant 1897), all continue to contribute positively to the group and setting values of a self-contained estate having historic connections with Captain Alexander Wadham Wyndham (1799-1869) of West Lodge, Dorset (NUIG); James Butler Stoney JP (1814-97); William Frederick Ormsby (1858-1941; NA 1911); the O’Malley family including Sir Owen St. Clair O’Malley KCMG (1887-1974) and Mary Dolling Sanders O’Malley (1889-1974), alias Ann Bridge, author of “Frontier Passage” (published 1942) and “The Dark Moment” (published 1952); and Walter Joseph Patrick Curley II (b. 1922), one-time American Ambassador Extraordinary and Plenipotentiary to Ireland (fl. 1975-7).

Rossyvera House, or Rockfleet [see Rossyvera entry], is near to the tower house of Carrigahowley. It has been suggested that it was originally a dower-house for the O’Donel family, who lived at Newport House (Newport is a small village, ten miles west of Castlebar in the northeast corner of Clew Bay). [p. 181] However, there is an account that it was built ‘as a nice neat house’ by a family by the name of Arbuthnot.
“In the 19th century the house came into the possession of the Stoney family. They had come from England in the 17th century and in the 19th century James Stoney (1814-1897), a Justice of the Peace, is known to have lived at Rossy-Vera (as it was spelt). His family cannot have owned the house after his time because James’s elder son, Thomas, resided at Oakfield Park, near Raphoe in County Donegal.
“The next name that is associated with Rossyvera is that of Sir Owen St. Clair O’Malley. Sir Owen described himself as ‘an autochthonous Irishman’ and was one fo the O’Malleys of Belclare. This branch of the family lived at Hawthorn Lodge (or Tallyho as it was originally named), near Castlebar in Co Mayo. One of this family was created a Count of the Holy Roman Empire and another, Loughlin O’Malley, conformed to the Established Church in 1718. His great-grandson, Peter O’Malley, QC, moved to England in the mid 19th century and became the Recorder of Norwich. His son, Sir Edward, was variously Attorney General of Jamaica and Hong Kong and eventually Chief Judge of H.M. Supreme Consular Court for the Ottoman Empire. Sir Owen O’Malley was Sir Edward’s son. He entered the diplomatic service in 1911 and the next year married Mary Saunders. …
On Sir Owen’s retirement, he and Lady O’Malley began remodelling and enlarging Rossyvera – it is recorded that Sir Owen built the additions with his own hands. They added a two-bay wing to the original three bay house, an extra storey with a flat roof, as well as a cupola on the top of the staircase hall. There is an elliptical hall and a spiral staircase, the three original reception rooms are now four – one of which is an octagon shape – and there are nine bedrooms. The library bookcases and the dining room chimneypiece are made out of macacauba wood, an exotic oriental timber used by Sir Owen to make cases for his possessions when he moved from Portugal to Ireland. [182] with view to reusing the timber, he instructed his packers to employ screws rather than nails when fastening the timber.
In the 1950s Sir Owen O’Malley and the O’Malley clan Association restored Carrigahowley Cstle (which had been used, at one period, by a family called Flynn for storing hay) and it is now a National Monument. He wrote a history of the O’Malley lordship in the 16th century in The Galway Archaological and Historical Journal (1950).
Sir Owen sold Rockfleet (the name is a contraction of the anglicization of Carrigahowley) in 1955, and moved to Oxford, where he died in 1974, a month after his wife. The new owner of the house was Carmel Snow, the editor-in-chief of Harper’s Bazaar, and the doyenne of fashion writers during the 1930s and 40s… she restored its original name of Rossyvera.
In 1957, Rossyvera was bought by Walter P. Curley and his wife, Mary. After a successful career in venture capital, Walter Curley served as Ambassador of the US to Ireladn from 1975-1977 and later, from 1989-1993 as Ambassador to France. .. He and hisw wife now live at Rossyvera for several months a year.”
