The Marquette Harbor Light is located on Lake Superior in Marquette, Michigan, a part of the Upper Peninsula. It is an active aid to navigation.
Construction of the current structure began in 1865. The 11⁄2-story dwelling shares its design with the lighthouses on Granite Island, Gull Rock and Huron Island. It includes a set of cast-iron spiral stairs winding from the first floor to the lantern centered on the square gallery atop the tower, a decagonal cast-iron lantern was installed, and a new fixed white Fourth Order Fresnel lens with a 190° arc of visibility was assembled atop its cast-iron pedestal. The focal plane is at 70 feet above the lake, and was visible for a distance of 10 nautical miles in clear weather.
