The Hudson–Athens Lighthouse, sometimes called the Hudson City light, is a lighthouse located in the Hudson River in the state of New York in the United States. The light is located between Hudson on the east bank and Athens on the west, closer to the Hudson side. Constructed in 1874, it marks a sandy ridge known as Middle Ground Flats and also acts as a general aid to navigation of the river. The station is built on a granite caisson with an unusual shape designed to protect it from ice floes and river debris. The dwelling is constructed in the Second Empire architectural style, with a mansard roof. It is considered to be virtually a twin of the Stepping Stones Light in Long Island Sound, which was constructed just a few years later.
