Behind the Wilson-Warner and Corbit-Sharp Houses is the Wilson Barn, often referred to as the stable. It was constructed of imported stone in 1812 at a time when brick or wooden buildings were the rule as little natural stone could be found in central and southern Delaware. An engraved stone under the stable eave speaks to the durability of the structure from its first 65 years to the present: "Built 1812, Rebuilt 1877."
The wood water pump in front of the Historic Pump House c.1780 is indicative of the public nature of the center of town. The pump was a necessity for thirsty travelers who otherwise would have had to beg a drink from a resident or purchase it at a livery stable or tavern.
