Old Oswestry Hill Fort

Old Oswestry Hill Fort is one of the finest Iron Age hill forts in Britain and the starting point for understanding the prehistoric landscape around the town. The fort was constructed and elaborated between approximately 600 BCE and 100 CE, beginning as a single-rampart enclosure and developing over centuries into the extraordinary multi-rampart complex visible today: five concentric rings of earthen banks and ditches, covering 68 acres on the flat-topped hill 1.5 miles north of the present town centre.

At its peak, the fort was a major settlement — estimates suggest a population of several hundred people within its banks, farming the surrounding land, trading in the regional exchange networks of the late Iron Age, and maintaining the elaborate system of defences that still dominates the landscape. The fort was not simply a refuge in times of war but a permanently occupied community centre, with evidence of circular houses, grain storage, and craft working within the ramparts.

The Bronze Age Landscape

Old Oswestry was preceded by an even earlier use of the same hilltop: the Bronze Age (roughly 2500–700 BCE) left burial mounds — round barrows — in the landscape around the hill and on the surrounding ridgelines. Bronze Age people buried their dead under earthen mounds, sometimes with grave goods of pottery, bronze tools, and occasionally gold, and these mounds survive in considerable numbers in the upland areas around Oswestry.

On Llanymynech Hill, 7 miles south, Bronze Age and Iron Age settlement evidence has been identified alongside the later iron-working. The limestone quarrying of later centuries has obscured some of the prehistoric landscape here, but the hill has a long human history predating the Roman period by several thousand years.

The Romans

The Roman conquest of the area began in the mid-1st century CE. Viroconium Cornoviorum — modern Wroxeter, 20 miles south-east of Oswestry — was established as the civitas capital of the Cornovii tribe around 90 CE and became the fourth-largest Roman city in Britain, with a forum, baths, amphitheatre, and a planned street grid. The remains at Wroxeter include the most substantial standing Roman masonry in England outside Hadrian’s Wall: the great fragment of the exercise hall of the bath house, known as “The Old Work”, stands 9 metres high. Wroxeter is managed by English Heritage and is open to visitors.

The Roman road system connected the region to the wider empire: Watling Street — now largely followed by the A5 through Oswestry — ran westward through the Marches toward the legionary fortress at Chester. A Roman presence in the Oswestry area itself is probable, though no major Roman settlement has been identified in the town.

Exploring the Prehistoric Landscape

Old Oswestry Hill Fort is the essential first stop and is freely accessible at any time — managed by English Heritage, open access. Llanymynech Hill (7 miles south) provides a further focus for prehistoric and ancient landscape exploration. Wroxeter Roman City (20 miles south-east) is the most substantial Roman site in the region. For the broader Bronze Age landscape — burial mounds, field systems, and ancient trackways — the Shropshire Historic Environment Record (available online) provides a comprehensive mapping of known sites. The Ordnance Survey maps of the area mark many of the visible earthworks.
