During a series of extensive rescue excavations, ahead of development in Dover’s town centre, undertaken by Kent Archaeological Rescue unit a substantial chalk block structure was excavated and recorded. This building appears to pre date the construction of the Roman Saxon Shore fort, as the soils of the southern rampart overly the remains. It is likely that it is contemporary with the earlier fort of the Classis Britannica, approximately 50m to the east of its eastern wall. (location accurate to the nearest 2m based on available information).
