Oheka Castle spanning over 109,000 square feet with 127 rooms, the French-style chateau—designed by Delano & Aldrich and nestled atop Long Island’s highest hill—is steeped in Gilded Age opulence.
Around the grounds, the famed Olmsted Brothers landscaping includes formal sunken gardens, reflecting pools, tennis courts, greenhouses, and even an 18-hole golf course—revealing the magnitude of its original vision.
