Chepstow Town Wall and Gate is a medieval defensive structure encircling the town of Chepstow in Wales. Built to protect the settlement that grew alongside Chepstow Castle, the fortifications comprise stone-built walls and gateways characteristic of late medieval urban defences. The walls were constructed from locally quarried stone derived from the underlying Dinantian limestone bedrock, which provided abundant suitable building material. This geological foundation of limestone with subordinate sandstone and argillaceous deposits ensured the availability of durable stone for the substantial masonry work required.
The town walls reflect the strategic importance of Chepstow as a fortified settlement controlling passage across the River Wye on the Welsh-English border. The defensive system would have protected merchants, artisans and residents within the town whilst regulating access through the gateways. The surviving sections of wall and gates demonstrate the substantial investment in urban fortification during the medieval period, when such defences were essential to a prosperous market town.
The monument is protected as a scheduled ancient monument by Cadw, the historic monuments service of Wales, under reference MM002. The walls remain a significant physical record of medieval town planning and military architecture, standing on geology that shaped both their construction and the wider landscape of this strategically important border settlement.
