The Cannonball House has come to symbolize not only the Society, but the town of Lewes as well; previous uses included a restaurant, a laundry store and, for a time, the mayor's office. Harkening back to the town's rich nautical heritage, the Cannonball House is the home of The Lewes Historical Society's maritime museum. Nationally important pieces of maritime art and memorabilia are displayed in the house, including the Fresnel Lens of Fourteen Foot Bank Light.
