Built against the southern rear face of the Wall, the fort was defended by 6 metre thick turf ramparts and surrounded by defensive ditches.

Causeways were then constructed across the main Antonine and secondary defensive ditches, affording easy access to and from the fort.

[3] Inscriptions found on recovered artefacts indicate that the fort based 480 men of the Cohors VI Nerviorum of Nervii, foot soldiers drawn from a north-eastern Gallic tribe.

The military road on the south side of the Wall, which enabled transport between all forts, is still well defined and there is also a fine length of rampart and ditch still intact to the west.

[5] A series of pits were discovered during the excavations lying to the north west of the causeway across the Antonine ditch.
