Overview

History & context

Cicutio, more commonly known today as Y Gaer (or Brecon Gaer), was a Roman auxiliary fort situated at the confluence of the Usk and Yscir rivers, approximately three miles west of modern Brecon. Established c. AD 75 during the Flavian campaigns against the Silures and Ordovices, it was initially a turf-and-timber fort covering roughly 7.5–8 acres, rebuilt in stone in the early 2nd century, and remained in use — with periods of reduced occupation — into the late 3rd or early 4th century. A garrison of around 500 men, including at one point the Cohors II Hispana (an attested cavalry unit), was based here.
