Meta CEO Mark Zuckerberg has bought a 19th-century Gothic-style castle overlooking a river in Southeast Ireland, according to a spokesperson. This castle—called Strancally Castle– is located 200 kilometres (125 miles) from his company’s European headquarters.
“Mark and his family are excited to continue caring for this historic home and look forward to spending time in Ireland, where Meta maintains its international headquarters,” Zuckerberg’s spokesperson, Brian Baker, said in an email statement to Business Insider.
The castle was bought from Michael Alen-Buckley, the cofounder of the London-based private investment firm RAB Capital, and his wife, Giancarla. According to the Irish Times, while the property’s actual price is unknown, it estimates that Zuckerberg spent between 20 and 30 million euros ($23 and $35 million) for the estate.

The three-story castle was built between 1825 and 1835 for John Keily, a former conservative MP, according to a record by the National Built Heritage Service of Ireland. It was lavishly designed by the architects James and George Richard Pain, with a “brisk walk of four and a half minutes” needed to go from the dining room to the kitchen, according to the book The Houses of Ireland.
Business Insider said that a spokesperson told the outlet that Zuckerberg and his wife, Priscilla Chan, have been looking for an Irish home base for some time. The Meta CEO also owns several homes in the Crescent Park neighborhood of Palo Alto, a short drive from the Meta headquarters in Menlo Park.
The previous owners of the castle said in a statement “We are delighted that Mark and his family intend to build on our stewardship by continuing to invest in maintaining and enhancing the property and grounds as their home in a sustainable manner. We wish them and their family much happiness in this unique and blessed place.”

The Blackwater Valley where the castle is located also contains other historic estates, including Ballynatray House, which the entrepreneur James Dyson bought in 2024. Further north, John Collison, a co-founder of the technology platform Stripe, bought Abbey Leix, an estate in County Laois, in 2021.
Not everyone is pleased with Zuckerberg’s acquisition. Some have expressed concerns, citing the disruptions in neighborhoods where he had previously acquired property. According to reports from last year, local residents complained about “eight years of constant construction, blocked driveways and debris,” after Zuckerberg spent more than $110 million to purchase properties around his 5,600-square-foot home on Edgewood Drive in Crescent Park neighborhood.
