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."
Georgian houses displayed a strict symmetry with a paneled door as a centerpiece capped by an elaborate crown or pediment. The decorative crown (entablature) and fanlight transom window are indications of the Corbit's wealth.
