Welsh Tourist Board

Chepstow, on its rock above the swirling waters of the River Wye, stands guard over a strategic crossing point into Wales. Started not long after the Battle of Hastings by William Fitz-Osbern, a companion of William the Conqueror, it was a landmark in more ways than one.

Built to secure Fitz-Osbern's new territories in the Welsh borders, Chepstow was the first of Britain's stone-built strongholds. Started during the infancy of castle building, it was improved throughout the centuries right up to the Civil War and beyond. As such, it is one of the few castles in Britain which traces the evolution of medieval military architecture from start to finish.
