GUY'S CLIFF, in Warwickshire, a great cliff on the west side of the Avon, 1 mile N. of Warwick. Here in the time of the Saxons there was a hermitage, to which Guy, earl of Warwick, is said to have retired from the world. This hermitage was kept up till the reign of Henry VI, when Richard Beauchamp, earl of Warwick, established there a chantry, in which he erected a statue in memory of the famous Guy, at the same time raising a roof over the adjacent springs.
