The Lewes Architectural Walking Tour is offered on a few Fridays during the summer by the Lewes Historical Society. (I've taken several of their tours now, all are excellent.)
The homeowner was outside as we walked past and she graciously invited us into what is most likely one of the oldest standing structures in Delaware. What a thrill! It was amazing!:
