Oheka Castle, also known as the Otto Kahn Estate, is a hotel located on the North Shore of Long Island, in West Hills, New York, also known as the "Gold Coast," a hamlet in the town of Huntington. It was the country home of investment financier and philanthropist Otto Hermann Kahn and his family. The name "Oheka" is an acronym using the first several letters of each part of its creator's name, Otto Hermann Kahn, which Kahn also used to name his yacht Oheka II and his ocean-front Villa Oheka in Palm Beach, Florida. The mansion, built by Kahn between 1914 and 1919, is the largest private home in New York, and the second largest in the United States, comprising 127 rooms and over 109,000 sq ft (10,100 m2), as originally configured. The castle is now a hotel with 32 guest rooms and suites. It is a popular wedding venue for socialites, celebrities, and dignitaries, as well as the backdrop to many photo shoots, television series and films. It also offers a bar, restaurant, and mansion tours of the estate and gardens. In 2004, Oheka was listed on the National Register of Historic Places. It is a member of Historic Hotels of America, the official program of the National Trust for Historic Preservation. From Wikipedia
