Petit Manan Light stands on an exposed island site off the Maine coast, where isolation shaped a self-sufficient lighthouse station of tower, keeper’s house, boathouse, and service buildings. A light was first established there in 1817, and the present granite tower was built in 1855, with the keeper’s house added in 1875. Rising 109 feet, it is Maine’s second tallest lighthouse tower. Storms repeatedly battered the structure, prompting repairs and reinforcement, including iron tie rods in 1887. After automation in 1972, its original Fresnel lens was removed. Now within the Petit Manan Wildlife Refuge, the historic station is closed to the public.
