Oheka Castle, also known as the Otto Kahn Estate, is a hotel located on the North Shore (or "Gold Coast") of Long Island, in West Hills, New York, a hamlet in the town of Huntington.

In 1948, Eastern Military Academy purchased the castle and 23 acres (9.3 ha) of its property, bulldozed the gardens and subdivided the rooms.

In 1946 the golf course and stables became part of the Cold Spring Country Club,[6][7] and the greenhouse complex operated as Otto Keil Florist.

In 1988, unable to continue financing the massive project, Melius sold the property to Japanese businessman Hideki Yokoi for $22.5 million (equivalent to $50,000,000 in 2023).

[9] They were unable to sustain the property themselves, so Melius reacquired it under a long-term lease and later re-purchased the estate, operating it as a weddings and events venue, luxury hotel and conference center.

[10] Celebrities who have been married there include Curtis Martin, Kevin Jonas,[11][12] Megyn Kelly,[13] Joey Fatone,[14] Brian McKnight, former U.S. congressman Anthony Weiner,[15] and comedian Yannis Pappas.
