During extensive rescue excavations undertaken across Dover’s Town centre by Kent Archaeological Rescue Unit a large sewer was located in the south east corner of the CLBR fort at the Battle of Britain Homes Site in 1971. Its east and west arms followed the line of the fort walls and were al total of 10.5m in length. The western arm originated in the nearby latrine block (B33). The sewer fed into the central culvert which led through the fort wall in the centre of its south-eastern corner. (location accurate to the nearest 2m based on available information)
