Plum Island Range Lights, Range lights in Door County, United States.
The Plum Island Range Lights are two navigation towers on Plum Island that guide ships through the Porte des Morts passage, one of the most dangerous straits in the Great Lakes. The rear tower features an iron structure, while the front tower has a skeletal frame design, and together they create alignment marks that sailors use to find safe passage.
An early lighthouse began operations on the island in 1849, but proved inadequate for guiding vessels safely through the dangerous passage. The two range lights were established in 1897 as a superior navigation solution for ships traveling through the strait.
The range lights shape how people understand Plum Island's role in Great Lakes shipping and mark an important part of maritime heritage that visitors can see while exploring the area. Local mariners and travelers recognize these structures as symbols of the region's dependence on water routes for connecting communities.
Visiting requires access by private boat or taking a scheduled ferry from Gills Rock, which operates on a seasonal basis. Plan your visit for daytime hours when you can see the structures clearly and navigate the island safely without difficulty.
The rear tower retains its original 1896 iron structure, while the front tower was replaced with a modern design in 1964 to improve efficiency. This combination of old and new elements reflects how maritime navigation technology adapted over the decades.
