The mortared flint and chalk foundations and well-preserved floors of a 14th century building were excavated. The structure was surrounded to the south and east by a courtyard with barrels located within the yard. The lower parts of the barrels were well preserved. Slaked lime in some of the barrels is indicative of the liming of skins. The building was rebuilt in the 15th century and demolished in the early 17th seventury with a new structure built and a series of large tanning pits cut through the demolished building.
