Eagle Harbor Light

Eagle Harbor Light is an operational lighthouse at Eagle Harbor, in Keweenaw County in the state of Michigan. It sits on the rocky entrance to Eagle Harbor and is one of several light stations that guide mariners on Lake Superior across the northern edge of the Keweenaw Peninsula. The original lighthouse, built in 1851, was replaced in 1871 by the present red brick structure, which is a Michigan State Historic Site and listed on the National Register of Historic Places.
