History & context

Caerau, in mid-Wales (Powys), was an auxiliary fort established in the Flavian period around 75 CE during the Roman conquest of the Silures and Ordovices, and was held into the mid-second century before being abandoned. The site comprises a roughly 2.5-hectare fort suitable for a 500-strong auxiliary unit (cohors quingenaria), together with associated marching and practice camps in its vicinity.

Significance

Historical significance

Caerau formed part of the network of forts strung across central Wales linking Caersws, Castell Collen and the upper Wye–Severn corridor, helping to police the Welsh uplands and control movement between the coast and the interior. Its accompanying camps suggest it also served as a training or staging point for troop movements through this strategically awkward terrain.

Archaeology

Archaeological record

The fort and several temporary camps have been identified primarily through aerial photography and earthwork survey, with the defences and internal layout traceable as cropmarks; no large-scale modern excavation has been published, so dating relies on limited surface finds and comparison with better-known Welsh auxiliary forts such as Castell Collen and Pen y Gaer.
