Longing for a fairy-tale wedding but lacking the requisite castle? Consider OHEKA Castle and Estate in Huntington, New York, one of many architectural masterpieces around the country available as a backdrop to your big day. Situated on 443 acres at the highest point on Long Island, the chateau-style residence, which once served as an elaborate summer home, cost $11 million dollars to build—back in the 1920s. That’s the equivalent of more than $110 million today. Lavish parties, many for royalty, Hollywood stars, and heads of state were commonplace here.
