There is some evidence that the vallum eastern limit was the Siret River.
The regiment was transferred from Dacia to Britain not later than 125, when it was stationed briefly at Fort Fanum Cocidi (Bewcastle, Cumbria) and appears to have participated in the excavation of the so-called Vallum, a huge ditch running along the near side of Hadrian's Wall (constructed 122-8).
The village is situated on the course of a vallum associated with Hadrian's Wall and is near the narrowest point of the River Eden, the site was a crossing point for Roman troops, Scottish border raiders, and cattle drovers.
The commune Valu lui Traian (formerly Hasancea) is named after the vallum.
