Ty Lettice Roman road is a Roman road in Wales protected by Cadw under reference RD260. The road follows a course across terrain underlain by Llandovery Rocks, a geological formation of Silurian age comprising sandstone and conglomerate beds. This solid foundation of interbedded sedimentary rock would have provided good drainage for the metalled surface typical of Roman roads in Britain.
Roman roads in Wales formed part of the military infrastructure developed during the occupation, linking forts and settlements across difficult upland country. The Llandovery formation's varied composition of harder and softer stone layers would have influenced construction techniques, with engineers selecting suitable material from local sources where possible to build the road's distinctive cambered surface and drainage ditches.
The road's survival as an archaeological monument reflects both the durability of Roman engineering and the stability provided by its solid bedrock foundation. The monument's protection recognises its importance as evidence of Roman activity and communications strategy in Wales, where such roads remain among the most substantial surviving remains of the occupation period.
