Oheka Castle

Almost a century ago, financier and philanthropist Otto Hermann Kahn built OHEKA Castle in the middle of a 443 acre plot on the highest point on Long Island in Cold Spring Harbor, for an estimated cost of $11 million dollars ($110 million dollars in today’s currency). At the time of its construction, the French-style chateau was, and still is today, the second-largest private residence ever built in America. During the Gilded Age of the 1920’s, Kahn used the 109,000 square foot, 127 room estate as a summer home where
he hosted lavish parties and regularly entertained royalty, heads of state,
and Hollywood stars.
