Mark Zuckerberg, CEO of Meta, and his wife Priscilla Chan have acquired Strancally Castle — a sprawling 19th-century Gothic Revival estate in County Waterford, Ireland. The purchase, confirmed by a spokesperson for Zuckerberg on Thursday, August 20, 2026, marks the tech billionaire’s latest high-profile real estate investment in Europe.
A Historic Estate with Modern Significance
The three-story, stone-built castle sits on a 440-acre estate along the Blackwater River. Designed by renowned Irish architects James and George Richard Pain around 1830, it was originally built for John Keily, a former English Conservative politician. Described in the book Houses of Ireland as a lavish residence — so vast that it reportedly takes “four-and-a-half minutes to walk from the kitchen to the dining room” — Strancally has long been admired for its architectural grandeur and storied past.
From Aristocratic Roots to Tech Leadership
Zuckerberg purchased the property from the Allen-Blakely family, who had extensively restored it over the past 25 years. Though the sale wasn’t recorded in public land registries, The Irish Times estimates its value at between $23 million and $35 million. The castle is located approximately 190 kilometers from Meta’s international headquarters in Dublin — a hub where the company employs around 1,500 people and operates a major data center.
Ireland has long served as a strategic European base for U.S. tech giants, drawn by its historically low corporate tax rates and favorable regulatory environment. Meta’s presence in Dublin reflects this broader trend, and Zuckerberg’s acquisition underscores a growing personal connection to the country.
A Residence — Not a Relocation
Zuckerberg and Chan are expected to maintain their primary residence in the United States and use Strancally Castle as a private retreat during visits to Ireland. As stated by Zuckerberg’s spokesperson: “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.”
The estate joins a cluster of elite properties in the region, including Ballynatray House — purchased in 2024 for roughly $34 million by British business magnate Sir James Dyson, founder of the Dyson technology company.
A Castle with a Darker Past?
Some historical accounts lend an eerie dimension to Strancally’s legacy. English author William Howitt, who died in 1879, alluded to a grim history tied to the site — possibly referencing its earlier association with Desmond Castle, a medieval stronghold once used by the Earls of Desmond across Ireland. In his writings, Howitt described how “the unwary, when lost within the castle, were bound hand and foot and hung over the murder hole — the rushing river swept away their gasping cries, and the dead told no tales.” While such claims remain unverified folklore, they add a haunting layer to the estate’s centuries-old narrative.
