Romans are only known to have founded one town in Wales, Venta Silurum (Caerwent) in Monmouthshire, although the fort at Moridunum (Carmarthen) was later superseded by a civilian settlement. The modern-day Wales is thought to have been part of the Roman province of "Britannia Superior", and later of the province of "Britannia Secunda", which also included part of what is now the West Country of England.
