Originally installed on Arrowsic Island in 1898, with an adjacent keepers cottage, Doubling Point lighthouse was moved to a granite pier offshore in the following year. A wooden footbridge connected the lighthouse to the island. It is an octagonal wooden tower some 23 feet high. It served the shipbuilding in nearby Bath, and continues to serve guiding US warships. By 1902, a fifth-order Fresnel lens had replaced the original lantern, and this was replaced in the 1970s, and is now on display in the Shore Village Museum in nearby Rockland.
In around 2000/2001, the crumbling granite foundation was repaired and the delightful walkway restored. As you can see, when we visited, in 2011, the lighthouse and walkway were being re-painted. Thankfully, the lighthouse is now protected being on the National Register of Historic Places.
The keepers cottage and out buildings. Note the old bell tower to the left of the cottage in the right hand picture. The bell was moved into the lighthouse tower when it was moved offshore. The bell tower is now a garage.
