South Fox Island Light at the north end of Lake Michigan developed from an 1867 brick lighthouse with an attached keeper’s dwelling into a larger light station with fog signals, assistant keepers’ quarters, service buildings, and, in 1934, a relocated steel skeletal tower from Sapelo Island, Georgia. The station adapted over time with new walkways, electrification, and automation before the light was discontinued in 1969. Because the isolated complex remained standing, it preserves a rare combination of an 1860s brick light and a 20th-century steel tower on the same shore. Restoration efforts since the 1980s have helped safeguard this historic site.
