Kenilworth, a market-town of Warwickshire, on a small sub-affluent of the Avon, 5 miles N. of Warwick and 5 SSW. of Coventry. The castle, founded about 1120 by Geoffrey de Clinton, was defended for six months (1265-66) by Simon de Montfort's son, and passed by marriage (1359) to John of Gaunt, and so to his son, Henry IV. It continued a crown possession till in 1563 Elizabeth conferred it on Leicester, who here in July 1575 entertained her for eighteen days at a daily cost of £1000 - that sumptuous entertainment described in Scott's Kenilworth. Dismantled by the Roundheads, the castle has belonged since the Restoration to the Earls of Clarendon. Its noble ruins comprise 'Caesar's Tower,$ the original Norman keep, with walls 16 feet thick; Mervyn's Tower and the Great Hall, both built by John of Gaunt; and the more recent but more dilapidated Leicester's Buildings. There is a fragment also of an Augustinian priory (c. 1122); and the parish church has a good Norman doorway. Tanning is the chief industry. Pop. (1851) 2886 ; (1901) 4544.
