The name "Venta" gave its name to the emerging Kingdom of Gwent, and the town itself became known as "Caer-went" or "Castra/Fort of Venta/Gwent". Tradition holds that Caradog Freichfras of Gwent moved his court from Caerwent to Portskewett during the second half of the 6th century, finishing in this way the last romanised presence in Wales.
