St. Martin Island Light is an exoskeleton lighthouse that marks one of four passages between Lake Michigan and the bay of Green Bay.[10] Constructed in 1905, this light tower is the only example in the US of a pure exoskeletal tower on the Great Lakes. Similar designs exist in Canada.[11] Painted white, the hexagonal tower is made of iron plates which are supported by six exterior steel posts that have latticed buttresses.[4][12]
The cream city brick lightkeeper's house was modeled after that used for the Plum Island Range Lights.[4]
It was listed on the National Register of Historic Places on July 19, 1984, Reference #84001387 as St. Martin Light Station (U.S. Coast Guard/ Great Lakes TR). It is not on the state list/inventory.[13] A steam fog signal was also installed.[14] which was thereafter replaced by a diaphone.[4]
The lighthouse keeper's dwelling has been abandoned and "is in poor condition."[12]
The light station is closed to the public. It is managed by in partnership with the Little Traverse Bay Band of the Odawa Indian Nation.[11][15]
