Kenilworth Castle, Kenilworth, Warwickshire
The first castle was built here soon after the Norman Conquest, and the impressive keep (seen here) survives. Simon de Montfort held the castle in the mid 13th century, while in the 17th century it was the home of Robert Dudley, Earl of Essex and favourite of Queen Elizabeth. Many of the buildings date from this period. This property is now in the care of English Heritage (2010).
