Who built the Roman forts?

Abstract

When dealing with the construction of forts, one gains the impression that this was a task generally carried out by legionaries, although most arguments for this are based upon legionary tile-stamps found within auxiliary forts. Many inscriptions, however, prove the involvement of a large number of auxiliary troops. This paper attempts to outline the sources and collate the building inscriptions of the Roman provinces, in order to decide conclusively whether the auxiliaries merely functioned as assistants.
