An official Path Through History Site! Montauk Point Lighthouse Museum is a National Maritime Historic Landmark and contains a museum, tower, and gift shop. This is the oldest lighthouse in New York State, completed in 1796 on a spot where the Royal Navy had maintained signal bonfires for its ships during the American Revolution. Congress appropriated $255.12 in 1794 to buy the site. Three years later, President George Washington authorized the construction of the lighthouse after many ships had been lost on the reefs at land's end. The Coast Guard operates the beacon, which was automated from Fresnel lens to 1,000-watt airport-type beacon in 1987. Located at the easternmost tip of Long Island.
