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 remained unexcavated at Dover. The first example of this is the Principia or headquarters which would have likely been situated on the west side of the north-south Via Principalis, the line of which is determined by the northern gatehouse (B13).
