About St. Martin Island Lighthouse
The St. Martin Island Light, a unique exoskeleton structure, was built in 1905. This hexagonal iron tower stands 23 meters tall and is supported by six exterior steel posts with latticed buttresses. It is the only known example of a pure exoskeletal tower design on the Great Lakes in the United States. A cream city brick keeper's house, modeled after the Plum Island Range Lights, was also constructed. The light emits a white and red signal. A steam fog signal was initially installed and later replaced by a diaphone. The keeper's dwelling is currently in poor condition and the light station is closed to the public.
Why it matters: This lighthouse marks one of four passages between Lake Michigan and the bay of Green Bay. It is recognized as a Michigan state historic site.
