The Manistee Pierhead lights are active navigation lights at the harbor entrance in Manistee on Lake Michigan, marking the channel from the north and south piers. A first light on the south pier was established in 1870 but was destroyed in the Great Fire of 1871. Replacement lighthouses were built in 1875, and the structures were later moved and rebuilt as the harbor evolved. The current north pier light, dating from 1927, is a cast-iron tower with a lantern, fog signal, radio beacon, and a rare surviving catwalk. Still serving navigation, it is also a recognized historic landmark preserved by the City of Manistee and cared for by the Manistee County Historical Museum.
