SUPERIOR, Wis. — The Superior Entry lighthouse is for sale. It is one of three lighthouses being auctioned off by the U.S. General Services Administration as part of the National Historic Lighthouse Preservation Act.

An online auction for the Superior lighthouse began July 10 with a minimum bid of $10,000 required. As of Wednesday, July 17, there had been one bid for the Superior structure, which was built in 1913. No ending date has been set.

The lighthouse encompasses five stories: a basement, a two-story main area with living quarters and a light tower surmounted by a lantern. The light would continue to serve as an active navigation aid and remain the property of the U.S. Coast Guard, which will maintain an easement to service it.

Because the lighthouse sits at the end of U.S. Army Corps of Engineers breakwater, a lease from the Corps would be required.

In addition to the Superior building, the Poe Reef Lighthouse 6 miles east of Cheboygan, Mich., and the Ontonagon Breakwater Light on Michigan's Upper Peninsula are also being auctioned. Those sales began June 20 with starting bids of $50,000 and $5,000, respectively.

The National Historic Lighthouse Preservation Act has sold or transferred 139 lighthouses out of federal ownership since it began in 2000, finding new owners for the historic structures. Visit realestatesales.gov for additional information or to place a bid.
