Kenilworth Castle, Kenilworth, Warwickshire
The original castle at Kenilworth is thought to have been a motte and bailey which was replaced by a fortified keep and a curtain wall towards the end of the 12th century. In 1173-4 Kenilworth Castle was garrisoned for Henry II and became a royal castle. It was to be refortified and redesigned over several centuries. This property is now in the care of English Heritage (2011).
