Presque Isle Harbor Breakwater Lighthouse is located on the breakwater at the east side of Presque Isle Harbor in Marquette in Michigan’s Marquette County. It was built in 1941 at the end of the breakwater that extends 1,216 feet (370m) long. Visitors are welcome to walk the breakwater to the lighthouse except during storms, violent waves and turbulent water. Be sure to wear sturdy shoes as walking over the rocky portion of the breakwater becomes more difficult. The lighthouse sits across the Harbor from the accessible Clark Lambros Beach Park.
