The Racine Harbor Lighthouse was built in 1866. The one and a half story brick house had a tower embedded in the roof which contained a fifth order Fresnel lens. The lens was updated to a fourth order Fresnel lens in 1870. The lighthouse was decommissioned in 1901 and served as a keeper’s quarters for the North Pierhead Light. It was added to the National Register of Historic Places in 1975 and is now part of the Pugh Marina.
The historic lighthouse can best be viewed from the Lake Michigan Pathway boardwalk near the DoubleTree by Hilton hotel.
