The first castle at Kenilworth was built 50 years after the Norman conquest when Henry I gave the Royal Estate of Stoneleigh to Geoffrey de Clinton. Henry II took over the castle 50 years later, to counter an attack from his son’s rebel army. It was then extended by King John, who also transformed the lake into one of the Castle’s most illustrious features and the country’s largest manmade lake.
Kenilworth was almost destroyed by Parliamentary forces in 1649 to prevent it being used as a military stronghold. Ruined, only two of its buildings remain habitable today.
