The Highland Light (previously known as Cape Cod Light) is an active lighthouse on the Cape Cod National Seashore in North Truro, Massachusetts. It is the oldest and tallest lighthouse on Cape Cod. The grounds are open year-round, while the light is open to the public from May until late October, with guided tours available. It is owned by the National Park Service, and cared for by the Highland Museum and Lighthouse, Inc., while the United States Coast Guard operates the light itself. The United States Navy ship was named after the light. It is listed on the National Register of Historic Places as Highland Light Station.
