In 2001 the Repository for Dung was reconstructed based upon Washington’s writings which detail the buildings construction and use, historical documents that discuss fertilizer production, and archaeological excavations. The excavations, conducted from 1993-1995, discovered the cobblestone floor, foundations of the brick walls and postholes which supported the building. These details were incorporated into the reconstruction.
Today, the Dung Repository illustrates Washington’s desire to experiment with new practices that could boost crop production. While many visitors comment that it must have been an unsavory presence so close to the Mansion, the reconstruction offsets the overly-sanitized view of 18th-century life that is often presented at historic sites.
