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). Subsequently a large part of the building had been removed by the Burlington Hotel. Most of the south-west wall survived, with parts of the north-west and south-east walls providing internal dimensions 5.88m (NW-SE) by a minimum of 0.75m (NE-SW). Remains of the entrance at the west corner survive with evidence of external steps leading down from the south-west. The walls are built of large greensand lumps, with some knapped flint and occasional chalk and caen stone, set in a hard cream-white sandy mortar with chalk/lime fragments. Traces of a red brick floor set on a cream whit mortar bedding were located, but this had been largely robbed before the cellar was infilled. Virtually all of this infilling had been removed by later post medieval work on the site and there were no dateable finds. (1)
