It is possible that this small Roman fort on the south side of the Wnion valley overlooking Dolgellau from the east was located at a junction of Roman military routes. The fort platform with rounded corner-angles is easily discernable in fields to the north of the line of the Roman road running south-west from Caergai (Margary 66b), which met with the Roman road running south-south-east from the fort at Tomen y Mur (Margary 69b) somewhere in the Dolgellau area. The main coastal route (M. 69b) almost certainly continued south-south-west to the Roman fort and Settlement at Pennal, but there is not much evidence for the actual route it took southwards nor the location of the road junction.
