Cadw's description

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

The monument comprises the best preserved and most visible stretch of defences of the Roman Town of Carmarthen. It forms part of the southern end of the eastern side of these defences which have been shown to consist of an earthen and turf rampart with an external ditch. The present surface of the site shows a marked drop to the east where the rampart drops towards the ditch.

The monument is of national importance for its potential to enhance our knowledge of Roman defensive organisation and of the growth of towns. The monument forms an important element within the wider Roman context and the structure itself may be expected to contain archaeological information in regard to chronology, building techniques and functional detail.

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