Drum Point Lighthouse dominates the museum's waterfront. This screwpile, cottage-type light is only one of three remaining from forty-five that once served the Chesapeake Bay at the beginning of the twentieth century. Decommissioned in 1962, the lighthouse fell victim to vandals until moved to its present site in 1975. Beautifully restored, complete with furnishings of the early twentieth century, it has become the waterfront's main attraction and is listed on the National Register of Historic Places. Tours are guided, and the schedule varies seasonally (temporarily closed).
The Calvert Marine Museum acquired the Cove Point Lighthouse in 2000. However, because this is still an aid-to-navigation, the United States Coast Guard is still responsible for its official operation. The museum plans to maintain the lighthouse with the intention of creating one of the country’s most important maritime heritage centers.
The Cove Point Lighthouse is now open as a weekly vacation rental and special event site.
