Sandpiper Hill House Windmill
The Sandpiper Hill Windmill, constructed in 1928 as part of a Gilded Age mansion, was a Dutch-style windmill replica located on Long Island's South Fork at Ditch Plains in Montauk, New York. After the mansion fell victim to beach erosion, the windmill was purchased and moved by artist and photographer Peter Beard to his property in Montauk.
