Cowbridge was a small castra in Roman Wales within the Roman province of Britannia Superior. Today the contemporary settlement, Cowbridge, has a population of roughly 3,600. Its name in Latin is unknown, although it is the strongest candidate for Bovium (corrected from the ablative Bomio) of the Antonine Itinerary. Its remains have been discovered beneath Cowbridge in the Welsh county of Vale of Glamorgan, previously Glamorganshire.
