The Windmill, a rare and remarkable Cape Cod waterfront estate on a private peninsula, surrounded by sandy ocean beach on Nantucket Sound and the shore of the picturesque Herring River, is tucked away at the end of an exclusive enclave. Available for the first time in over 70 years, this extraordinary property comprises the main Windmill House, featuring a breezeway whose walls of windows open to breathtaking views of both ocean and river; a vacant oceanfront lot; a riverfront cabin with kitchenette and bathroom; and an impressive thirty-foot T-shaped deep-water dock with 3 boat slips. Wide pine floors, hand-hewn beams and fireplaces lend Old World charm inside the 5-bedroom, 3-bathroom Windmill House, architecturally inspired by traditional English windmills, and designed for gracious living. Outside, spacious settings for outdoor entertaining and resort-level resources complete this once-in-a-lifetime opportunity that is quintessentially Cape Cod.
