Carmarthen Roman Town is a Roman settlement established in south-west Wales, occupying a strategic location above bedrock of Arenig rocks composed of mudstone, siltstone and sandstone. The underlying geology provided stable ground suitable for permanent military and civilian occupation during the Roman period in Britain. The town developed as an important administrative and trading centre, taking advantage of its riverside position.
The site represents a key example of Roman urban development in the Welsh frontier region, where the military presence required supporting infrastructure and civilian settlement. The preserved remains form part of the broader archaeological landscape of Roman Wales, reflecting the empire's expansion and control across the province. Structures and deposits accumulated across several centuries of occupation.
Today, the Roman Town at Carmarthen is protected as a scheduled ancient monument under Cadw, the Welsh heritage organisation, with the reference CM234. This statutory protection recognises the archaeological significance of the buried remains and ensures ongoing preservation of this important record of Romano-British settlement, settlement patterns and daily life in the western provinces of Roman Britain.
