Beavertail Lighthouse, built in 1856, was and still is the premier lighthouse in Rhode Island, USA, marking the entrance to Narragansett Bay. The 64-foot (20 m) lighthouse lies on the southernmost point of Conanicut Island in the town of Jamestown, Rhode Island in Beavertail State Park, on a site where beacons have stood since the early 18th century. The Whistle House and Garage were destroyed by the New England Hurricane of 1938. The light provides navigation for boats and ships entering Narragansett Bay in the East Passage between Conanicut Island and Newport, Rhode Island on Aquidneck Island.
