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 (3.0 m) high and weighed several tons (tonnes).
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.
When these lights were built, there was no way to produce a flashing light and, occasionally mariners would confuse one light for another with disastrous results. The only way to create a distinction was to build more than one light. There were two lights at Plymouth and three at Nauset Beach. Gradually as it became possible to create flashes with a revolving lens system, the multiple lights were discontinued, so that while the south light is an active, Coast Guard maintained light, the north tower was discontinued in 1932. It was relighted as a Private Aid to Navigation in 1989. The south light is now owned by the Town of Rockport and managed by the Thacher Island Association; the north light is owned by the US Fish and Wildlife Service.
The station was added to the National Register of Historic Places as Twin Lights Historic District – Cape Ann Light Station on October 7, 1971, reference number 71000355. In 2001 they became the 9th light station to be recognized as a National Historic Landmark.
