Mark Zuckerberg and Priscilla Chan Buy Historic Irish Castle for $57 Million

Meta CEO Mark Zuckerberg and his wife, Priscilla Chan, have expanded their global real estate portfolio with the acquisition of Strancally Castle, a historic 19th-century estate in County Waterford, Ireland.

News According to Ireland’s Property Price Register, the transaction was officially recorded on August 17, 2026, at a price of €51.17 million (approximately $57 million)—making it the highest-priced residential property sale in Ireland this year. While the registered figure covers the 16,000-square-foot Gothic Revival mansion and up to one acre of land, the complete property encompasses a sprawling 440-acre estate overlooking the River Blackwater, suggesting the total cost of the wider deal may be even higher.

Located in southeast Ireland roughly 200 kilometers from Meta’s European headquarters in Dublin, the property will serve as a private base for the couple and their family during visits to the country. Prior to the sale, the estate was owned and extensively restored over a 25-year period by RAB Capital co-founder Michael Alen-Buckley and his wife, Giancarla.

In a statement confirming the purchase, a spokesperson for Zuckerberg said the family is “excited to continue caring for this historic home and look forward to spending time in Ireland”. Additionally, Zuckerberg and Chan have pledged €150,000 in community funding to be split equally among three local Gaelic Athletic Association (GAA) sports clubs in the area.
