West Quoddy Head Light

West Quoddy Head, in Quoddy Head State Park, Lubec, Maine, is the easternmost point of the contiguous United States. Since 1808, there has been a lighthouse there to guide ships through the Quoddy Narrows. The current one, with distinctive red-and-white stripes, was built in 1858, and is an active aid to navigation. Photographs and paintings of this lighthouse are frequently reproduced. The 3rd order Fresnel lens is the only 3rd order and one of only eight Fresnel lenses still in use on the Maine Coast.
