During extensive rescue excavations undertaken across Dover’s Town centre by Kent Archaeological Rescue Unit, the southern end of a substantial structure representing a barrack block (B25) was located under which was situated a small ditch running roughly north-north-west by south-south-east, at the Battle of Britain Homes site in 1971. This ditch is sealed by the walls and floor of the period one barrack block and obviously predates the earliest building at this location.
