Doubling Point Light

Doubling Point Light is a lighthouse on the Kennebec River, in Arrowsic, Maine. The Doubling Point light was established in 1898, fifteen years after the founding of the Bath Iron Works, a major shipbuilder, one and a half miles upriver. It was part of a major upgrade of the river's lights — the Doubling Point Light and the separate Range Lights on the point, Perkins Island Light, and Squirrel Point Light were all built at the same time.
