Port Washington Light in Port Washington, Wisconsin, began in 1849 as a separate brick tower and keeper’s house overlooking Lake Michigan. It was rebuilt starting in 1859 as a two-story brick lighthouse dwelling with a roof tower, and its lighting equipment evolved from Lewis lamps to Fresnel lenses with an increased range. The station served generations of keepers, including Charles Lewis Sr. and Charles Lewis Jr., but became redundant after the breakwater light was first lit in 1889 and was discontinued in 1903. Later remodeled for harbor service, it was restored after 1993 and now operates as a museum, with a replacement tower and lantern donated by Luxembourg as a World War II memorial.
