Such milecastles were thought to have been constructed by the Legio VI Victrix who were based in Eboracum (York).

[2] A causeway over the wall ditch (not necessarily primary) may have existed at the location of the milecastle.

Subsequent examination in 1959 revealed a turret with an original floor of clay and mortar, which had been overlain in part by stone.

A small area, delineaeted by kerbs, existed throughout the life of the turret, though its usage remains unknown.

Finds indicating evidence of bronze casting where unearthed, including a crucible and a whetstone.

Unusually, some of these fragments were identified to have been manufactured by Legio VI Victrix near York around 120AD, suggesting they may have built the turret.
