Kenilworth Castle is the largest castle ruin in England. The castle has lost what was once its most striking feature, the great lake, a kilometre long and half a kilometre wide, which practically surrounded the medieval castle.

Although now in ruins, you can still see the red sandstone remains of the Norman keep, John of Gaunt's Great Hall, and the residential buildings Robert Dudley built for the visiting Queen Elizabeth, as well as a restored Tudor garden and Tudor stables.
