Chryssanthie, Lady O'Reilly (née Goulandris; also known as Christina;[citation needed] 27 June 1950 – 23 August 2023) was a Greek-American businesswoman who was one of the richest women associated with Ireland.
Goulandris studied French civilisation and art history at the Sorbonne in Paris, then returned to New York, working in the family offices, her business activities ranging from silver futures trading to horse breeding.
Goulandris died suddenly in Normandy on 23 August 2023, at the age of 73[2] (she had been receiving treatment for breast cancer but had been attending the horse sales in Deauville the previous day and had mingled with buyers and sellers from Ireland and elsewhere earlier in the week).
Although not tax resident in Ireland, one of her main homes was Castlemartin House and Estate near Kilcullen, County Kildare, which included a horse stud facility and a Charolais cattle-breeding operation.
Her official main residence was a house in the closed executive development of Lyford Cay near Nassau, the Bahamas; others were a complex on the southern coast of Ireland at Shorecliffe, Glandore, County Cork, and a Georgian townhouse on Fitzwilliam Square, Dublin, and a chateau in Deauville, France.
Goulandris owned, bred, trained and raced horses under a number of house names, including at least Castlemartin Stud (shared with her husband), Petra Bloodstock Agency, Skymarc Farm.
In 1993, Goulandris was appointed to the board of the Irish National Stud by the Minister for Agriculture, and in early June 1998, she was made its chairperson by Joe Walsh, in succession to David Shubotham.
