Description

The monument comprises the surviving earthworks of the Roman road travelling NE from the fort at Caerau to the fort at Castell Collen. The Roman road is now only visible as an earthwork situated within enclosed pasture between SN 9356 5169 in the SW and SN 9367 5177 in the NE. The earthwork is visible as an agger, or raised embankment, measuring c.5.5m in width and up to 0.2m in height, flanked on either side by a shallow ditch that measures between 1m and 1.5m in width. The primary Roman road network was designed and constructed by the Roman army for the purpose of military conquest and rule. Roads were built and used throughout Roman Britain from the mid 1st century AD onwards. In Wales, the majority of the Roman road network dates from the Flavian-Trajanic conquest and garrison (between AD 74 and AD 117).

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 structure itself may be expected to contain archaeological information in regard to chronology and building techniques.

The scheduled area comprises the remains described and an area around them within which related evidence may be expected to survive. It is linear and measures 150m from NE to SW by 10m transversely.
