The Roman site at Llanfor lies just outside Bala on the northern flood-plain of the Afon Dyfrydwy (River Dee) at the north-eastern end of Llyn Tegid (Bala Lake).

The fort measures about 650 feet from east to west by 600 feet transversely (c.198 x 183 m), between the ditches, therefore enclosing an area of almost 9 acres (c.3.6 ha). The defences consisted of a substantial rampart fronted on all sides by three ditches. There were only three gateways, that in the east side is centrally placed. The defences of the fort overlie the south-eastern defences of the legionary-sized temporary camp, proving that the fort was the later addition, its large size perhaps again attesting a legionary garrison. The fort's turf and timber defences show no trace of rebuilding.
