Overview

Rural remains of a major military outpost

Looking at its tranquil location in farmland near Brecon today, you’d never guess that Gaer was once one of the Romans’ largest inland forts and a vital link in the occupiers’ defensive network in Wales. Founded around AD 75, it was situated in a strategic position at the meeting point of two major roads and manned by highly trained legionaries of the Vettonian Spanish Cavalry Regiment.

In Roman times this was a busy site, with a large guardhouse, granary and heated bathhouse. Today you can see remains of a number of defensive towers, alongside two large gateways with walls standing 8ft/2.4m high in places.
