Oheka Castle

Oheka Castle is a historic Gold Coast mansion in Huntington on Long Island, New York. The estate was built for financier and philanthropist Otto Hermann Kahn, with construction beginning in 1914 and the building completed in 1917. Its name comes from the first letters of Otto Hermann Kahn. Built on the highest point on Long Island, the French-style château was designed by Delano & Aldrich, with grounds designed by the Olmsted Brothers. At 109,000 square feet and 127 rooms, Oheka Castle remains one of the largest private residences ever built in the United States. After Kahn’s death, the estate passed through several uses, including a retirement home, a radio operators’ school and a military academy, before falling into serious disrepair. It was bought by Gary Melius in 1984 and restored over several decades. Today, Oheka Castle operates as a hotel, restaurant, wedding venue and filming location.

Oheka Castle has appeared in film, television and music videos as mansions, European estates, country houses, elite retreats and fictional palaces. Productions connected to the location include Citizen Kane (1941), The Emperor’s Club (2002), What Happens in Vegas (2008), Gossip Girl (2007–2012), Royal Pains (2009–2016), Louie (2010–2015), The Americans (2013–2018), Madam Secretary (2014–2019), Madoff (2016), Succession (2018–2023), The Diplomat (2023–), Dexter: Resurrection (2025–) and Taylor Swift’s “Blank Space” music video (2014). Its château-style exterior, formal gardens, grand staircase, ballrooms, dining rooms and long driveways have made it especially useful for stories involving wealth, power, old money and social performance.

In Citizen Kane (1941), Oheka Castle appears as part of Xanadu, the vast private estate of Charles Foster Kane. The castle is used in the film’s opening montage, where Xanadu is presented as an almost mythic monument to wealth, isolation and personal obsession. The use of Oheka Castle helps establish the scale and unreality of Kane’s private world before the story moves into the mystery of his life and final word.

In The Emperor’s Club (2002), Oheka Castle is used for the “Mr. Julius Caesar” rematch. The film follows classics teacher William Hundert and his complicated relationship with student Sedgewick Bell, and the later rematch brings the characters back into a formal, elite setting. Oheka Castle’s grand interiors and estate atmosphere fit the film’s themes of privilege, education, reputation and moral failure.

In What Happens in Vegas (2008), Oheka Castle appears as part of the film’s Long Island material. The romantic comedy mostly moves between Las Vegas and New York, but the castle gives the film a brief image of upper-class Long Island grandeur. Its exterior and estate setting contrast with the film’s more chaotic comedy of accidental marriage, money and romantic conflict.

In Gossip Girl, Oheka Castle appears in “Gone Maybe Gone”, episode 1 of season 6. The castle is used for the European scenes involving the characters after the events of the previous season, standing in for glamorous locations outside New York. Its gardens, formal architecture and château-like appearance fit the series’ world of wealth, secrets and international privilege, while still keeping the production within New York State.

In Royal Pains, Oheka Castle is used as Shadow Pond, the mansion of Boris Kuester von Jurgens-Ratenicz. The location becomes one of the series’ most important recurring estate settings, connected to Boris, his wealth and his complicated medical and personal storylines. The castle’s grand rooms, terraces and grounds give the show a convincing Hamptons-style world of extreme privilege, even though the real estate is in Huntington on Long Island.

In Louie, Oheka Castle appears as the setting for a charity event where Louis C.K. and Jerry Seinfeld perform. The location’s formal event-space character fits the episode’s comedy of status, discomfort and social performance, turning the castle into a place where entertainment, money and awkward public behaviour meet.

In The Americans, Oheka Castle is used for scenes connected to diplomacy, intelligence work and high-level political manoeuvring. The mansion’s formal rooms and estate atmosphere fit the series’ Cold War world, where private meetings, public appearances and hidden motives often occupy the same space. The castle gives these scenes the controlled, official quality of a location tied to power and international politics.

In Succession (2018–2023), Oheka Castle appears in “Hunting”, episode 3 of season 2. The estate stands in for the Hungarian castle where Logan Roy takes the Waystar Royco executives on a corporate retreat. The castle’s isolated, aristocratic atmosphere becomes central to the episode, especially during the dinner sequence that leads to the infamous “Boar on the Floor” humiliation game. The location makes the retreat feel removed from ordinary corporate life, turning the Roy family’s power games into something more feudal and grotesque.

In Dexter: Resurrection (2025–), Oheka Castle appears in “Course Correction”, episode 7 of season 1. The castle is used for Leon Prater’s serial-killer retreat, where Dexter, using the name Red Schmidt, is brought together with the remaining members of Prater’s private circle. The location’s grand rooms, estate atmosphere and secluded Long Island setting make the gathering feel both luxurious and deeply threatening. The episode uses the castle as a controlled arena for Prater’s power over the group, while Dexter studies the other killers and eventually turns the situation to his advantage and where he confronts the Gemini killer. Oheka Castle gives the episode one of its most striking locations, placing the violence and manipulation inside a setting associated with wealth, privilege and old-world grandeur.

In Taylor Swift’s “Blank Space” music video, Oheka Castle is the main setting for the fantasy romance and breakdown between Swift’s character and her lover. The castle, gardens, staircases, dining spaces and bedrooms create a world of extreme wealth and theatrical romance, which gradually turns into jealousy, destruction and revenge. The video uses Oheka Castle almost like a pop-gothic palace, making it one of the most recognisable modern screen appearances of the estate.
