Cape Ann Light Station Thacher Island, Massachusetts: The Story of America's Last Operating Twin Lights
The Cape Ann Light Station on Thacher Island off the coast of Rockport, Massachusetts, is noted for some very significant firsts and lasts in the history of light stations in the U.S. It was the first lighthouse to mark a dangerous spot along the coast. The nine prior lighthouses simply marked harbor entrances. The original station was the 10th of the twelve stations built under British rule. The current towers are the last officially operating twin lights in the nation.
