During extensive rescue excavations undertaken across Dover’s Town centre by Kent Archaeological Rescue Unit, extensive remains of the Classis Britannica Fort were uncovered and recorded, these included parts of all four of the walls, two gate houses, numerous drains and sewers and at least nine of the internal structures of the fort. From this evidence it is clear that the arrangements broadly reflect the standard layout of a Roman auxiliary fort and it is therefore possible to ascertain the locations of the structures and features which are commonly located within Roman forts but have remained unexcavated at Dover. In almost every axillary Roman fort investigated, there is a building of varying form which is normally described as the Commandant’s House, most often it occurs near the Principia. It is therefore likely that this structure would have been in the south-west corner of the CLBR fort at Dover, in an area which remained un-investigated through these works. (location accurate to the nearest 50m based on available information).
