The site of the medieval manor house may be represented by the traces of moats west and north what was Kempton Park House. The first recorded visit of a sovereign to Kempton was that of Henry III in 1220. He came to Kempton often in the next two decades and less frequently in the later part of his reign. Jousts were held "in Kempton field" in 1270. Edward I visited Kempton comparatively rarely and later kings seldom or never went there. Many apparent references to their visits in the 14th and 15th centuries (perhaps too the jousting mention) seem to be Kennington which was closer to the convenient grouping of courtiers' customary London homes and lettings. The lord of Kempton granted the great tithes of the manor to Grestain Abbey in Normandy before 1104.
