Henry III. was much at Kenilworth, and the sheriff’s accounts show large and frequent expenditure very early in his reign. In 3 Henry III., a chapel was built, probably in the outer ward, and £150 allowed to rebuild a tower that had fallen. In each year more or less is spent. In 5–7 Henry III., the wind was high, and blew down several trees in the park, and much damaged certain buildings in the castle. Wine was occasionally sent there from Southampton. In 13 Henry III., the bank of the pool was repaired, and two years later there were more repairs, and mention is made of a gaol delivery by the judges. King John had already used the castle as a prison. In 19 Henry III., £6 16s. 4d. was allowed for a fair and beautiful boat to lie near the door of the king’s great chamber. No doubt the king had by that time constructed the dam and formed the lake. In 22 Henry III., Archbishop Walter de Gray had temporary charge of the castle, to receive there Ottoboni, the papal legate, who was himself soon afterwards placed in charge of it. In 26 Henry III., more money was spent. The chapel was to be ceiled with wainscot and painted, and seats provided for the king and queen. The tower where the bells hung was to be repaired, a new wall built on the south side by the pool, and the queen’s chamber to be painted. No doubt the Water Tower and the early part of, and perhaps the additions to, Mortimer’s Tower were of this period, as well as the dam and the outworks beyond it. Henry seems to have completed the military works pretty much as they are now seen.
