During excavations undertaken by Canterbury Archaeological Trust, ahead of the rebuilding of the Townwall Street filling Station, Dover, a complex series of stratified archaeological deposits were revealed representing activity at the site between the early Medieval period and later post medieval periods. Period 4 consists of some somewhat fragmentary post medieval remains which largely consisted of wall footings relating to buildings and garden boundaries. Post war clearance of the site appears to have truncated most of the associated stratified remains. Cartographic and documentary evidence shows that a large mansion once stood in the area of the present site. Some of the remains recorded in the excavations have been equated with this important building and its associated structures. These include possible wall footings of the mansion itself, a culvert, a boundary wall along Clarence Street and garden walls. (Location accurate to the nearest 1m based on available information)
