Kenilworth Castle is a magnificent stone motte and bailey fortress, the largest castle ruin in England. In the inner bailey stands a massive Norman keep, with its huge forebuilding, John of Gaunt's 13th century great palatial buildings and Robert Dudley's interesting 16th century range of buildings. In the outer bailey are the Earl of Leicester's gatehouse and a long range of stables. All defended by a high curtain wall, with round and polygonal flanking towers, two lakes and a great barbican with earth and stone flanker's. 5 miles south is Warwick Castle and 5 miles north-east is Baginton Castle.
