Thomas Point Shoal Lighthouse is probably the best-known lighthouse in Maryland, and it has many distinctions. It’s the last surviving screwpile lighthouse in Chesapeake Bay, and it’s one of the few lighthouses in the United States to be designated a National Historic Landmark. It’s weathered many storms but it’s now in need of help.
John Potvin is a member of the Chesapeake Chapter of the United States Lighthouse Society. He has been a volunteer at Thomas Point Shoal Lighthouse for several years. As the preservation foreman, he is actively involved in the bidding and specification preparation for the rehabilitation of the lighthouse, as well as coordinating volunteer schedules and tasks.
In this episode of Light Hearted, host Jeremy D’Entremont and co-host Michelle Jewell Shaw also look at the origins and history of screwpile lighthouses, which were developed by the Irish engineer Alexander Mitchell.
