Walnut Hill is a historic home located in Campbell County, Virginia. The building is notable mainly for its Georgian architecture and its many structures. Its architectural significance is from the original building and frame remaining. It was listed on the National Register of Historic Places in 2000. The land was initially owned by the Clark family, who obtained it by a land grant from King George III. The property also stood witness to events in the Civil War. A "drill field" or muster ground is said to have existed at Walnut Hill during the war, located on the low ground along Flat Creek at the southeast end of the property.
