BORRIS HOUSE, Borris, County Carlow, is the ancestral home of the MacMorrough Kavanaghs.
Borris is one of the few Irish estates that can trace its history back to the royal families of ancient Ireland.
Originally an important castle guarding the River Barrow, Borris House was rebuilt in 1731 and later altered by the Morrisons, chiefly Richard and William.
Externally, they clothed the 18th century house in a thin Tudor-Gothic disguise, adding a crenellated arcaded porch on the entrance and decorating the windows with rectangular and oval hood-moulds.
Inside the mansion they created an exuberant series of rooms, beginning with the most florid room of the house, the entrance hall, where a circle is created within a square space with the clever use of pairs of scagliola columns and richly modelled plasterwork.
The ceiling is like a great wheel with its shallowly-coved circular centre, from which eight beams radiate outwards.
The plasterwork is profuse with festoons in the frieze, eagles with outspread wings in the spandrels and swirling acanthus in the cove of the ceiling.
Major MacMorrough-Kavanagh had no male issue.
Before his sudden death, in 1953, he had been working on setting up a trust to ensure the future of the Borris estate.
The trust had not been finalised, and he had not made a will.
The result was a high burden of death duties and legal costs, which led to the sale of some family treasures.
Among the items sold was an unfinished Rubens. It was sold for £23,000 and has since been sold for something in the region of £1,000,000.
In 1958, the house faced the threat of becoming a ruin when Joanne Kavanagh, following the death of her second husband, Lieutenant-Colonel Archibald Macalpine-Downie, decided to vacate the big house and move to a smaller new house on the estate.
The house had been so rebuilt, altered, and enlarged that it was now almost impossible to maintain.
Joanne Kavanagh's only son, Andrew Macalpine-Downie, after a career in England and his marriage to Tina Murray, returned to Borris and assumed the family surname, Kavanagh.
Other former seat ~ The Lodge, Ballyragget, County Kilkenny.
