Venta Silurum is a rare example of a tribal ‘capital city’ where the assimilation and acculturation of native peoples following their conquest by the Roman army can be studied and understood from remarkably intact archaeological remains. Venta Silurum was 1 of only 2 cities in Wales; the other was founded at Carmarthen (Moridunum) as the tribal capital of the Demetae tribe (the Roman remains lie beneath the modern town).

Caerwent is a site of international significance. Extensive excavations over the past 120 years or so have produced unique evidence for the history of the Roman city and the lives of its inhabitants. Much of the area within the city’s walls is a Scheduled Monument and the village is also at the centre of a designated Conservation Area and an Area of Special Archaeological Sensitivity.
