Cape Ann Light (Twin Lights)

Local nameCape Ann Light (Twin Lights)
LocationEssex County, Massachusetts, United States

The Cape Ann Light Station on Thacher Island, off Cape Ann in Rockport, Massachusetts, is nationally significant as the last light station to be established under colonial rule and the first station in the United States to mark a navigational hazard rather than a harbor entrance. The current pair of lighthouses were built in 1861. They were both equipped with first order Fresnel lenses, which stood approximately 10 feet high and weighed several tons.

After being decommissioned in the early 1980s, the lens from the south tower was moved to the U.S. Coast Guard Museum at the United States Coast Guard Academy in New London, Connecticut. In 2013 a joint effort by the Cape Ann Museum and the Thacher Island Association brought the lens back to Cape Ann. The first order lens is now on display at the Cape Ann Museum in Gloucester, Massachusetts.
