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 3 (c. 1550-1780) represents an increase in activity across the site, a series of buildings was constructed along Clarence Street (B47-51 and B53) with a cellared structure further to the south-east (B46). Building 46 consisted of a stone lined cellar, 1.2m deep, it presumably relates to a dwelling which would have been located on the north-east edge of the excavated area, beyond plot H. It was dug through period 1 deposits but cut across by later stone walls belonging to Clarence House (period 4). (location accurate to the nearest 1m based on available information).
