During extensive rescue excavations undertaken across Dover’s Town centre by Kent Archaeological Rescue Unit, substantial remains of the Classis Britannica fort were uncovered and recorded. Excavations in an area which was originally occupied by the Cause Is Altered Public House near Princes Street (Cause Is Altered Site) in 1971, revealed the remains of main road running through the centre of the fort; the Via Principalis, which was located immediately to the east of the east granary.
