Cadw's description

The following provides a general description of the Scheduled Ancient Monument.

The monument is comprised of buried features and earthworks representing part of the Roman fort at Carmarthen. The primary Roman fort network was designed and constructed by the Roman army for the purpose of military conquest and rule. Excavations in recent years suggest that the Roman fort lay outside and to the west of the Roman Town, and most of the area is built over. This small area remains undeveloped and the depth of the archaeological levels below modern ground level suggests that preservation of Roman strata is likely to be good.

The monument is of national importance for its potential to enhance our knowledge of Roman military organisation. The monument forms an important element within the wider context of the Roman occupation of Wales and the structures may contain well preserved archaeological evidence concerning chronology, layout and building techniques.

The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
