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). To the south western end of the site, in an area which, in the later Medieval and early post medieval period, was occupied by East Brook Water, were a succession of mortared stone walls which create at least three enclosed areas.
