Blackistone Lighthouse

Historic Site

blank dot

The Blackistone Lighthouse, built in 1851 by master lighthouse builder John Donahoo, stood on the south end of the island serving Potomac River mariners until it was decommissioned in 1932. The vacant lighthouse was burned by vandals in 1956 and forever lost as an important monument to Potomac River heritage. However, through the efforts of the St. Clement's Hundred, a local community organization created for the preservation of St. Clement's Island, a replica of the Blackistone Lighthouse was constructed and completed in June 2008.

A water taxi service is available to and from St. Clement's Island. The St. Clement's Hundred provides volunteers for guided tours of the lighthouse, normally on weekends and special events during the warmer months. Call St. Clement's Island Museum for an updated lighthouse tours schedule at 301-769-2222. There is no fee for guided tours, but donations are gratefully accepted and are used for lighthouse maintenance expenses.
