What is known about Mark Zuckerberg’s purchase of the 19th-century Strancally Castle in Waterford, Ireland—including its estimated $23 million–$35 million price, 440-acre riverside estate, at least 11 bedrooms, four tower suites, library, dining room and drawing room, previous ow

Mark Zuckerberg and Priscilla Chan have bought Strancally Castle, a 19th-century Gothic estate in County Waterford, in an off-market deal. The purchase is confirmed, but the price has not been publicly disclosed; reported estimates range from about €20 million to €30 million, roughly $23 million–$35 million. 25

• The estate: Strancally sits on about 440 acres overlooking the River Blackwater. Reports describe a roughly 16,000-square-foot main house with at least 11 bedrooms, four tower suites, a library, dining room, and drawing room. 7815

• Seller: Irish reporting says the property was acquired from Michael and Giancarla Alen-Buckley, whose family owned it. 416

• Family use and preservation: A Zuckerberg spokesperson said that he 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. 3

• Connection to Meta: The castle is about 200 km (125 miles)—commonly characterized as roughly a two-hour drive—from Meta’s European/international headquarters in Dublin. Meta also has a data center in Clonee, County Meath; reports differ in how they describe its proximity and the relevant opening date, so it is safest to treat the “2017 Dublin data center” phrasing as imprecise rather than a confirmed reason for the purchase. 236

• Miami purchase context: Earlier in 2026, Zuckerberg and Chan were reported to have purchased a home on Indian Creek Island near Miami—an ultra-exclusive enclave where Jeff Bezos also owns property—for about $170 million. 14 Reporting linked that broader move to wealthy tech figures considering residences outside California amid a proposed state wealth-tax measure, but there is no evidence that the Irish acquisition itself was motivated by that proposal or that it represents a relocation from California. 37

The clearest reading is that Strancally is a private Irish base near Meta’s European operations and a historic property the family says it intends to maintain—not a disclosed corporate acquisition, tax-planning vehicle, or permanent residence.
