Kenilworth Castle Remains
The original castle is thought to have been a motte and bailey which was replaced by a fortified keep and a curtain wall towards the end of C12. In 1173-4 Kenilworth Castle was garrisoned for Henry II and became a royal castle which was to be refortified and redesigned over several centuries. In 1253 Henry III granted the castle to Simon de Montfort, Earl of Leicester, but following his death in 1265, the castle was surrendered to the king who granted it to his younger son, the Earl of Lancaster. Following John of Gaunt's marriage to Blanche, daughter of the first Duke of Lancaster, Kenilworth Castle passed to him in 1361 and he was responsible for upgrading it to become, in effect a royal palace. In 1533 the castle was granted to John Dudley, Duke of Northumberland, but following his execution, it returned to the Crown. The grant was renewed to his son, Robert Dudley, the Earl of Leicester and favourite of Elizabeth I, who made extensive changes.
