Pottawatomie Lighthouse, also known as the Rock Island Light, is located in Rock Island State Park, on Rock Island in Door County, Wisconsin. Established in 1836, it is the oldest light station in Wisconsin and on Lake Michigan. It was served by civilian light keepers from 1836 to the 1940s, at which point it was taken over by the US Coast Guard.
The lighthouse was restored by the Friends of Rock Island Lighthouse.[10] It is open for tours during the summer as the Pottawatomie Lighthouse Museum. The lighthouse has been restored to a state illustrating its appearance circa 1882-1910. The restoration was performed with the help from the non-profit Friends Of Rock Island State Park. It now serves as a museum that is open for tours daily from Memorial Day to Labor Day 10am to 4pm.
The lighthouse was listed as Pottawatomie Lighthouse in the National Register of Historic Places in 1979, as reference #79000074. The fresnel lens, lost after the lighthouse was shut down in the late 1980s, was replaced by a plexiglass copy in 1999. (via Wikipedia)
