The late Mr. Wykeham Martin, whose investigations of his hereditary fortress were a labour of love, seems to have established firmly, on sound critical grounds, the date of its several parts. He shows the high probability of its occupation by at least a Saxon lord, and the changes it has undergone from the Crevecœurs, Leyburns, and the Plantagenet and Tudor monarchs, who, from Edward I. to Edward VI., held it in possession. Like many Saxon strongholds, Leeds is thought to date from the ninth century. It was held, probably by a Norman arrangement, by castle-guard tenure under Dover. To Bishop Odo, who obtained it at the Conquest, is attributed some Norman work in the church, but the earliest masonry in the castle, probably represented by the curious vaulted cellar, is thought to be the work of Robert de Crevecœur, who founded Leeds Priory in 1119, and afterwards removed three canons into the chapel of his castle. A later Robert shared in the defeat of Lewes, and was in consequence obliged to yield up Leeds in exchange with Roger de Leyburn, a powerful Kentish baron, father of that William whose unscrupulous boldness is well described in the Roll of Caerlaverock, which designates him as “A valiant man, without ‘but’ or ‘if.’” Out of the disputes between the dispossessed and the dispossessor Edward seems to have established a title by the strong hand. He gave to the fief the character of a royal manor, was a frequent visitor at the castle, and appears to have completely remodelled the fortress of the Crevecœurs, giving it the aspect which in many points it presents at this day. By Edward it was settled upon the queen, part of whose funeral charges were incurred here in 1291. Here also the king founded a chantry in the castle chapel for her soul’s health, and it was about this time that he caused the bath to be constructed. Upon Edward’s second marriage Leeds was again settled upon his queen, and for several reigns this continued with some exceptions to be the practice. It was also much used for the reception of visitors of distinction who rested here on their way from Dover to London. In 1321 the king’s defences were put upon their trial. The castle seems to have passed by an exchange to Bartholomew de Badlesmere, a great lord, who in 1321 was away in the North plotting with other barons the fall of Despenser, while his wife and children remained in the castle, the Constable being a certain Walter Colepeper.
