Hammondsport is a village in Steuben County, New York, United States. First settled in 1792 the village is located at the south end of Keuka Lake, one of the Finger Lakes. Beginning in the 1790s the village began to take form, which included a courthouse and a jail. In the 1850s vineyards and the wine industry began to emerge in and around Hammondsport. Pioneer aviation engineer and pilot Glenn Curtiss was born in Hammondsport, where he built several types of aircraft, and the first seaplanes, which were tested in Keuka Lake. Hammondsport features a village square, historic buildings, wineries, breweries and museums. Nearby municipalities contain vineyards, and wineries and grape-packing have played a major role in the economy. In 1935, heavy rains lasting three days resulted in mudslides and major flooding, ruining or damaging many homes and structures in Hammondsport, situated at the hillside. A number of buildings surrounding Pulteney Square make up the Pulteney Square Historic District and are listed in the National Register of Historic Places
