High on a man-made hill overlooking Long Island’s Gold Coast, Oheka Castle tells a story of ambition, exclusion, and stunning architectural triumph. Built in 1919 by financier Otto Hermann Kahn, the 109,000-square-foot French-style château was more than a home—it was a message. Shared with the r/centuryhomes community, captivating readers with its blend of grandeur and grit. Shunned by the social clubs of the era, Kahn didn’t beg for entry—he built his own kingdom.
A Hill Raised for Power
Kahn, a German-Jewish banker who rose through the ranks of Kuhn, Loeb & Co., faced discrimination from Long Island’s elite. Denied entry into high society, he responded with architectural dominance. In 1914, he purchased 443 acres in Huntington and ordered the construction of an artificial hill, ensuring his future home would tower above every other estate on the Gold Coast.

From 1914 to 1919, architects Delano & Aldrich realized his vision: a 127-room château with 39 fireplaces, a 24-foot-high ballroom, and secret passageways. Costing $11 million at the time (about $158 million today), Oheka was built not just for comfort but for spectacle.

Where Jazz Age Legends Played
Once complete, Oheka became a stage for the elite to gather—on Kahn’s terms. The Olmsted Brothers (sons of Central Park designer Frederick Law Olmsted) sculpted 23 acres of formal gardens, complementing a golf course, tennis courts, stables, and greenhouses.

Kahn hosted royalty, U.S. presidents like Theodore Roosevelt, and opera legend Enrico Caruso. With a 200-person staff keeping the estate in motion, Oheka was a social powerhouse. Its influence extended into pop culture, even inspiring the fictional “Xanadu” estate in Orson Welles’ Citizen Kane.

From Ashes to Icon
Following Kahn’s death in 1934, Oheka passed through many hands. It served as a military academy, and by the 1970s, sat abandoned and ravaged by over 100 arson attempts. The grand interiors were gutted, and the future looked bleak.

But in 1984, developer Gary Melius purchased the ruins for $1.5 million and launched a $30 million restoration. By 1988, Oheka reopened as a luxury hotel and event venue. It’s hosted high-profile weddings, and even appeared in Taylor Swift’s “Blank Space” video in 2014.

A Castle That Still Commands Respect
Oheka Castle stands today as the second-largest private home ever built in the U.S., a monument not just to Gilded Age wealth, but to resilience and reinvention.

For r/centuryhomes followers, it’s a reminder that historic homes can carry powerful narratives—stories of exclusion, revenge, and the will to leave an indelible mark on history.
