Roman Road c. 250m SSW of Gilwen Farm is a Roman road preserved beneath the Welsh landscape. The route follows the underlying geology of Ashgill bedrock, composed of mudstone, siltstone and sandstone, which would have influenced both the Roman engineers' choice of alignment and the road's durability through time. These relatively soft sedimentary rocks, laid down in the Ashgill period, characterise the southern Wales terrain where this section of Roman infrastructure was constructed.
The road is located in a landscape that reflects its geological foundations, with the mixed lithology of the Ashgill rocks providing variable support for the metalled surface that would have been laid during the Roman occupation. Such roads were engineered with cambered surfaces and drainage systems to cope with the Welsh climate and underlying geology.
The monument is protected by Cadw, the Welsh Historic Monuments service, under reference CM369. This recognition reflects its importance as evidence of Roman road engineering in Wales, a key element of the infrastructure that supported military and commercial movement during the Roman period. The road's survival and identification demonstrate the lasting impact of Roman construction techniques on the Welsh landscape.
