Mark Zuckerberg has been quietly snapping up massive chunks of real estate for years.
The tech billionaire has bought hundreds of acres of Hawaiian land.
He also recently bought a castle in Ireland.
Mark Zuckerberg has amassed a real estate portfolio that has easily exceeded $100 million, but, until recently, he kept it within the confines of the US.
A spokesperson for Zuckerberg confirmed to Business Insider that he and his wife, Priscilla Chan, purchased a 200-year-old castle in Waterford County, Ireland.
“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 purchase price is unknown; however, The Irish Times, which first reported on the sale, estimates Zuckerberg paid between 20 and 30 million euros — or between $23 million and $35 million. A drop in the bucket for the Meta CEO, who has an estimated net worth of $192.4 billion, according to Forbes.

Zuckerberg owns a residential compound in Palo Alto.

It’s no surprise that a tech titan has more than one property in Silicon Valley. The Meta CEO owns five homes in the Crescent Park neighborhood of Palo Alto.
He gave viewers a rare peek inside one of them in 2016; the house is even tricked out with a “custom-made artificially intelligent assistant,” according to CNBC. The home is only a 10-minute drive from the Meta HQ in Menlo Park.
He bought the first Crescent Park property in May 2011 for $7 million.

Architectural Digest described it as a “‘no frills abode” that chooses function over extravagance. Zuckerberg then spent over $43 million on the four homes surrounding his original residence in Crescent Park, The Wall Street Journal reported.
He sold his San Francisco townhouse in 2022 for a reported $31 million.

The four-bedroom, four-bathroom home is located near San Francisco’s Dolores Park. He and his wife, Priscilla Chan, reportedly spent $10 million to purchase the townhouse in 2010.
He bought two adjacent estates on the shore of Lake Tahoe around 2019.

Lake Tahoe is a popular vacation destination for wealthy Californians in both summer and winter, and Zuckerberg and his family are no exception.
The tax records of the two properties — known as Carousel Estate and Brushwood Estate — display the same address as tax records of other properties linked to Zuckerberg, according to documents viewed by BI.
Zuckerberg reportedly paid $59 million for both properties.

At 5,322 square feet, the Brushwood Estate features six bedrooms, five baths, and two half baths, according to SF Gate. Inside are high-beamed ceilings and picture windows; outside are lush trees, a private dock, and a hot tub. There’s also a 2,293-square-foot guesthouse.
The Meta exec owns over 1,200 acres of land in Hawaii.
Business Insider tracked down at least 1,200 acres between 17 parcels of land that have the same tax address as other properties mentioned above, but are owned by LLCs includingKahu’aina Holdings LLC and Pila’a International LLC.
The 1,200 acres include about 750 acres he reportedly paid $100 million in 2014 for. That encompasses a more than 350-acre span of land on Pila’a Beach.
His plans for Koolau Ranch seem to be in preparation for the worst case scenario.
On one of his Hawaiian parcels, Zuckerberg is reportedly building a huge compound that’s said to include a 5,000-square-foot underground bunker with an escape hatch. It’s been dubbed Koolau Ranch, and Wired reported that buying the land and creating the compound cost the executive an estimated $270 million.
In March 2025, he purchased a 15,000-square-foot mansion in Washington, DC.

As Silicon Valley continues to infiltrate Washington, DC, Zuckerberg established a residence in the US capital, Politico said. The home that’s reportedly his new pad is situated in Massachusetts Avenue Heights, not far from the Naval Observatory and the Washington National Cathedral, according to Builder magazine.
Zuckerberg kept the purchase private, Politico said. The mansion in question was sold for $23 million in cash. It was designed by local firm Robert Gurney Architect and sits on about one acre of property.
Business Insider was unable to independently confirm that Zuckerberg purchased the property.

Mark Zuckerberg is reportedly adding a second East Coast property to his portfolio after buying a home in Miami, according to The Wall Street Journal.
Zuckerberg is said to be purchasing a waterfront mansion on Indian Creek, an exclusive island in South Florida that’s home to Jeff Bezos, Carl Icahn, and Jared Kushner.
It’s unclear how much this off-market deal was worth, but an empty lot next door to Bezos sold for $105 million in 2025.

In his first reported international buy, Zuckerberg purchased a three-story Gothic castle on 440 acres.
The castle, named Strancally Castle in Waterford County, Ireland, is about 140 miles south of Meta’s international headquarters in Dublin. It was built between 1825 and 1835.
Zuckerberg bought the castle from the cofounder of the London-based private investment firm RAB Capital for an undisclosed amount. The Irish Times estimates the castle sold for between $23 million and $35 million.
