In 1858 a 32-foot brick lighthouse was built on Mount Desert Island to mark the entrance to Bass Head Harbor and Blue Hill Harbor. The light is perched on a cliff. There was no boat landing at the site until 1894. A brick oil house was built in 1902 some 205 feet northwest of the lighthouse. It still remains at the site.
Also in 1902 a fourth order Fresnel lens replaced the original fifth order lens. The fourth order lens is still used in the light today.
While the light is on a national park, the Coast Guard uses it as a residence. The grounds are open to the public but the house is not. The light is an active aid to navigation. More info - lighthousefriends.c ... =512
