Status check, 2026-11: This is a pair of wooden towers built on Grassy Island in 1872 and switched off in 1966. They were moved ashore that year and then to the Green Bay Yacht Club breakwater in 1999. Sources give different heights (25/35, 26/36 and 22/29 ft), so height is left blank. Grassy Island Range Lights is listed on the National Register of Historic Places. It stands at 44.5363° N, 88.0049° W.
