Bulwark is a predominantly residential area of Chepstow, Monmouthshire, Wales, largely developed during the twentieth century. The area is so named because of its Iron Age fort, which is now maintained as a public open space. Substantial development in the area began during the First World War, with housing being provided for the military and civilian workforce brought to the area for the National Shipyard no.1 at Chepstow.
Bulwarks Camp, also known in the past as Hardwick Camp and locally as the Warren, is a small defensive hill fort, on top of cliffs overlooking the River Wye, the Beachley peninsula and the Severn estuary. It was probably built around the first century BC or the first century AD. The Romans called the inhabitants of the area the Silures; they would have spoken the language that became Welsh. The fort had cliffs to the east, a ravine to the south, and earthworks comprising a double rampart and ditch on the other two sides
