Beavertail Lighthouse, built in 1749, was and still is the premier lighthouse in Rhode Island, USA, especially for entrance into Narragansett Bay. The 45-foot (14 m) lighthouse lies on the southernmost point of Conanicut Island in the town of Jamestown, Rhode Island in Beavertail State Park.
In 1989, following a joint effort by the US Coast Guard, Rhode Island Parks Management, the Rhode Island Department of Environmental Management, and the town of Jamestown, the building was restored and reopened to the public. In 1993, Beavertail Lighthouse Museum Association (BLMA) was established to oversee the operations of the Beavertail Lighthouse Museum, which is located in the assistant keeper’s house. The museum includes a Fresnel lens (which I photographed and have displayed here), and the history of, models and photos of many Rhode Island lighthouses.
