Caus Castle, Medieval castle ruins in Westbury, England
Caus Castle is a ruined medieval fortification on a hilltop near Westbury, featuring a motte and multiple layers of earthwork defenses surrounding the site. The foundation remains and outer ramparts are still visible and reveal the former structure of the stronghold.
William the Conqueror granted land in 1069 to Roger le Corbet, who founded this castle as a stronghold. Over time it grew into a medieval market town with resident merchants and craftspeople.
The name comes from Normandy and reflects the Norman roots of the Corbet family who ruled this borderland region. You can see how medieval structures were built upon much older fortifications.
The site is freely accessible and you can explore the earthworks on foot, though the terrain is uneven. Wear sturdy footwear since the hillside can be steep and the ground becomes slippery after rain.
The stronghold was built upon an Iron Age hillfort, showing how defensive positions were reused across centuries. Earlier inhabitants recognized the same strategic advantage that the Normans would later exploit.
