Chambers Island Light is a lighthouse on Chambers Island in Door County, Wisconsin, that served as the island’s light until 1961, when a skeletal tower replaced it. That replacement remains the active aid to navigation, visible for 12 nautical miles, or about 22 kilometers and 14 miles, and is identified by the United States Coast Guard as 7-21895. The original lighthouse was formally recognized for its historical significance in 1975 through its listing on the National Register of Historic Places as reference number 75000063.
