In this narrow strip between the west wall of the stone fort, here
still not yet exposed, and the buildings of the vicus, is a narrow
strip within which the principal excavations of the pre-Hadrianic
fort have taken place. The photo looks north along the excavated
area. The remains of the earliest fort are stratified three to four
metres beneath the grass. The size of the accessible area, hemmed
in by well-preserved stone walls which must be left for display,
makes excavation very difficult.
