See Inside Oheka Castle, a 127-Room Estate Headed to Auction

If you’ve ever read or seen “The Great Gatsby,” you know 1920s New York was home to extravagant mansions with owners who hosted lavish parties — and if you’ve watched “The Gilded Age,” you know those parties began decades earlier in the 1870s.

And if you’re a really dedicated fan, you can own a piece of F. Scott Fitzgerald history yourself. Oheka Castle, a sprawling, century-old estate said to have inspired the parties in “The Great Gatsby,” is set to go up for auction on October 27, via Concierge and Adam Modlin of The Modlin Group.

Its original homeowner was financier Otto Hermann Kahn, who built Oheka Castle — named after its owner (Oh-He-Ka) — in 1919 on Long Island.

Kahn’s wife used to call the home “Otto’s zoo,” and it seemed to be an accurate description. A-listers of the time used to party at the 109,000-square-foot home, with Kahn as a Gatsby-like figure entertaining all his guests.

But Oheka’s journey didn’t end there. After Kahn’s death in 1934, the property changed hands numerous times until it was abandoned in the ’80s. Fires, vandalism, and theft devastated it.

According to Oheka Castle, land developer Gary Melius then purchased the estate and spent $40 million restoring it to its former glory. He defaulted on a loan over a decade ago, Forbes reported, and declared bankruptcy in July 2025 to forestall what’s happening now: Oheka on the auction block.

Today, it’s the second-largest private home in the US, behind only Biltmore House in North Carolina. It’s a popular venue for weddings, a restaurant, and a hotel, and has been featured in movies, TV shows, and music videos. Taylor Swift even filmed the “Blank Space” video there.

You can also tour the grounds for $30.

I took the tour in April 2024 and was astonished by the beauty of Oheka Castle. Here’s what it was like to visit.
