Venta Silurum of Roman Wales

In the village of Caerwent in the south of Wales stand the impressive remains of Venta Silurum, a market town established by the Romans in 75 CE. Named after the defeated local Silures tribe, it stood as their civitas capital during the Roman era in Britain. Established as an administrative centre, it was originally left undefended, until the second century when piratic raids led to the construction of basic defences for the now thriving town. These defences were later reinforced by the building of massive stone town walls and towers, which impressively still stand today largely intact.

This article explores the history of the ancient city of Venta Silurum. It is written as part of Odyssey Traveller’s series on lost ancient cities, with information drawn from Philip Matyszak’s Lost Cities of the Ancient World. The information is intended as background reading for our 22-day Roman Britain Tour for mature and senior travellers. During this tour, we explore the world of Roman Britain, occupied for some 400 years, with a lasting legacy of Roman sites, from roads to Hadrian’s wall to baths and more. Read on for more information about the Roman town Venta Silurum and the tour!

A New City

The Romans founded Venta Silurum in 75 CE, but not without strong resistance from the local tribe known as the Silures. Having invaded Britain in 43 CE, the Romans probably did not expect still to be fighting there two decades later. While the southeast fell reasonably quickly (and rose again briefly under Boudicca), the tribes in the highlands of present-day Wales fought the Romans every step of the way.

The Silures proved to be toughest nut for the Roman legions to crack. Ostorius Scapula, the second governor of Britain, proposed in frustration that the Silures should either be extirpated or moved wholesale to a different part of the empire. Scapula died in AD 52, exhausted by non-stop campaigning, and it took another generation before the Silures were forcibly persuaded to accept Roman rule.

Once they had pacified the Silures, the Romans moved the majority of the tribe’s remaining population from the hills and valleys of Gwent and Monmouth and moved them into the relatively flat – and much less defensible – lands of what is today the Vale of Glamorgan. It was here that they set up Venta Silurum as a small market town to act as the new tribal centre. The name translates as ‘the market of the Silures’, with ‘Venta’ having the same root as the modern word ‘vendor’.

The town was established essentially as an administrative centre for the defeated Silures, rather than for any military purposes. To make sure that the Silures continued to behave themselves, the Romans established a legionary base a day’s march away at Caerleon (Isca Augusta): not so close as to be oppressive, but near enough to quash any thoughts of making trouble. The Silures were considered as dediticii – people subject to Roman power who were neither slaves nor citizens.

The town was originally built on either side of the main road between Caerleon and Glevum (Gloucester). In this way the traffic could suitably impress the locals as the Roman’s military power and economic strength were paraded before them each day along the military supply route. Since it would defeat the purpose for which the town had been founded, the original site had no defensive walls.

The Growth of Venta Silurum

As the Pax Romana took root in Britain, Venta Silurum became an established civic centre, or civitas. At the height of the Roman Empire under the Antonine rulers of the second century, the town began to expand into a tidy little city.

There had always been a forum and a basilica, as these were part of the original function of the town (the forum as the marketplace and the basilica for administration and legal matters). Now, as the Silures were given increased control over their own affairs, the basilica was ornamented with Corinthian columns 8 metres (26 feet) high, and the civitas acquired an amphitheatre and public baths. A Romano celtic temple, possibly dedicated to Mars and the Celtic god Ocelus, was also built at a later date.

Eventually the growing sprawl along the road was regularized and the land was divided into some thirty residential plots, called insulae (literally ‘islands’) or City Blocks, of roughly equal size. The houses built on these plots were generally small and many served a dual purpose, consisting of shops or workshops at the front with living quarters in the rear. As time went on, some of the houses became larger and acquired luxury fittings such as mosaic floors and hypocausts (a type of underfloor heating highly desirable in the Welsh climate).

For the most part though the houses were simple and sparsely decorated. The Silures would never attain vast wealth and the refined Roman qualities that come with. In contrast to their wealthy close neighbours the Dobunni from Gloucestershire and Hereford & Worcester, who built many villas in the hills around their own civitas capital, there was no such pattern of villas surrounding Venta Silurum.

Even so, by the late second century the town was thriving, with a probable population of circa 2,000.. The location had now become valuable enough, and the Silures peaceable enough, to warrant the construction of an earthen ditch and rampart to defend the town against raiders. These initial basic defences enclosed and area of forty acres (eighteen hectares).

The Roman Retreat

Venta Silurum’s Roman connection was to come to an end in the third century, when the empire fell into a political and economic crisis. As a result the Second Augustan Legion was withdrawn from Caerleon. This may have prompted the building of massive stone walls in the mid-4th century. Surrounding the town in a rectangle, these walls may have originally reached a height in excess of eight metres (27 feet). Today, the walls are still standing largely intact, rising up to 5 metres (16 feet) in places.

With the increasing threat from Irish pirates raiding up the River Severn, square towers were then added to the south and north walls – six to the south and five to the north. Late military equipment found at the site suggests that the town was also defended by a military garrison.

Nevertheless, Venta Silurum suffered from a design fault that was, literally, built in – the location had been deliberately chosen because it was hard to defend. Once the Roman legions left Britain, Venta Silurum was no longer viable. Eventually the townsfolk were forced to acknowledge this fact, and by the mid-5th century they had retreated to the greater security of the nearby hills. A monastery was later established by Saint Tathan around the 6th century, but by then Venta Silurum had long ceased to exist as a civic entity.

Venta Silurum Today

Though gone, Venta Silurum continued to loom large in the consciousness of the local people. The name ‘Venta’ mutated into ‘Guenta’ and gave its name to the emerging Welsh Kingdom of Gwent (initially called ‘Kingdom of Guenta’). As Britain became less unruly, a village grew on the site of the former Roman-era settlement. The village it self was called Caerwent, or ‘The casta/fort of Venta/Gwent’.

Because for a long time no-one dared occupy the flat lands upon which Venta Silurum had stood, the Roman walls were not mined for stone, as happened in many other places. As a result, the site retains what are, by some distance, the most impressive Roman walls surrounding any town in northern Europe.

Most of Venta Silurum is an open-air museum, though a sizeable portion of the site still remains to be excavated. Visits are possible all year round and there is a dedicated parking area near the church, which contains many Roman artefacts from the lost city.
