Meta CEO Mark Zuckerberg has purchased Strancally Castle, a Gothic Revival estate in County Waterford, Ireland, for an estimated €20 million to €30 million Perth Now. The 16,000-square-foot, three-story castle sits on 440 acres along the River Blackwater, built around 1830, and the Zuckerbergs plan to use it as a personal residence during visits to Ireland while maintaining its heritage status.
Strancally Castle was constructed circa 1830 for Tory MP John Keily and designed by the renowned Pain brothers Canberra Times. The original estate featured a folly tower and an inlet quay along the River Blackwater near Youghal. The property underwent a two-decade restoration before the sale, with previous owners Alexander and Giancarla Buckley confirming the transaction after 25 years of stewardship.
The castle sits in an exclusive neighborhood along the Blackwater Valley Ulladulla Times. Nearby high-profile properties include James Dyson's Ballynatray House, purchased for approximately €29 million in 2024, as well as Lismore Castle and Salterbridge House.
