Kennebec River Range Light There were several lighthouses built in 1898 to help mariners navigate along the Kennebec River toward the ship building center of Bath. Originally known as the Doubling Point Range Lights and established on Arrowsic Island in 1908, the two wooden towers are the only range lights in Maine. The way the lights are aligned indicates to ships the middle of the channel on the approach to Fiddler Reach,which is a very sharp double bend of the river beyond Doubling Point. The front light is 21 feet high and the rear light is 13 feet high and are 235 feet apart from each other. Each one held a fifth order Fresnel lens, which were removed in 1979. The keepers house and towers are connected by a wooden walkway. The boathouse added in 1901 and the oil house in 1902. The bell tower stands between
