Kenilworth Castle

Kenilworth Castle stands in ruins today, but in its heyday it was a grand palace that left visitors in awe. It was expanded and rebuilt over the course of several centuries, from the 12th to the 16th, in a series of phases. What sets this castle apart is its scale, form, and the quality of its workmanship, making it the finest surviving example of a semi-royal palace of the later Middle Ages. It was the scene of the removal of Edward II from the English throne, the perceived French insult to Henry V in 1414 of a gift of tennis balls (said by John Strecche to have prompted the campaign that led to the Battle of Agincourt), and the Earl of Leicester's lavish reception of Elizabeth I in 1575.
