Caerwent (Welsh: Caer-went) is a village and community in Monmouthshire, Wales. It is located about five miles west of Chepstow and eleven miles east of Newport, and was founded by the Romans as the market town of Venta Silurum, an important settlement of the Brythonic Silures tribe. The modern village is built around the Roman ruins, which are some of the best-preserved in Europe. It remained prominent through the Roman era and Early Middle Ages as the site of a road crossing between several important civic centres. In the 20th century Caerwent was the site of a Royal Navy Propellant Factory, now used as a training facility.
