55 Sturgeon Bay Ship Canal (WI 30)

While Sturgeon Bay is on the West Side of  Door County, the boats travel the east side in the middle of Lake Michigan.  So they cut a canal through the peninsula, but clearly needed to mark it well.  This light (and the one below) illuminate the passageway for sailors.
