Brecon Gaer Roman Fort

Brecon Gaer is a Roman military fort in Powys with surviving stone walls, two gateways, and multiple defensive towers arranged in its original pattern. The site preserves the remains of buildings where soldiers lived and worked, allowing visitors to trace the layout of a complete Roman garrison settlement from its design.

The fort was established around 75 AD and served as a base for a Spanish cavalry regiment at the crossing of major Roman roads. It played a key role in controlling the eastern frontier of Roman Britain during the occupation.

The fort layout demonstrates Roman military engineering principles through its guardhouse, granary, and bathhouse structures that formed a complete military settlement.

The site is freely accessible and sits about 4 miles northwest of Brecon next to the A40 road. Visit in daylight hours when the ground layout and walls are easiest to see, and wear suitable footwear for walking on uneven terrain.

The northern wall contains some of the best-preserved Roman door pivot holes found in Britain, showing exactly how ancient doors were mounted and worked. These mechanical details reveal Roman engineering skill from nearly 2000 years ago that few visitors notice.
