A priory founded at the beginning of the reign of Henry II. by Robert de Wateville. It was augmented early in the reign of Henry III. by William de Percy. On William de Percy's death his heart was buried before the Lady altar in the church or chapel of this hospital, and here too was interred the body of his wife Joan.

Sandon Hospital.—In the beginning of the reign of Henry the Second, an hospital, or priory, was founded by Robert de Watevile in the parish of Esher, on a piece of ground adjoining the common called Ditton-marsh, where now is a farm styled Sandon farm. This hospital is said to have been dedicated to the Holy Ghost, though it is sometimes called the hospital of St. Mary and All-Saints; and in a writ issued by Henry the Third, respiting the payment of a tax, it is denominated the hospital of St. Mary Magdalen."

William de Perci, founder of the abbey of Salley in Yorkshire, gave to this hospital twenty marks a year, which that abbey paid him for his manor and forest of Gisburn; and also seven virgates of land, and one-twelfth of a knight's fee, in Foston, in the county of Leicester, amounting to eighty acres. The rent from Salley was to be paid until Perci, or his heirs, should make to the master and brethren of the hospital a compensation, in rents or lands, to the value of twenty-three pounds and half a mark: and in consideration of this gift, they were to maintain six chaplains, and keep a lamp and candle of two pounds weight continually burning before the altar of the Virgin Mary, in the hospital chapel, (where the heart of William de Perci, and the body of his consort, Joan, were interred,) during the time that any mass was said at any altar in that chapel, on pain of the bishop's censure, and distress on their lands by the heirs of the founder."

In the years 1348 and 1349 a terrible pestilence desolated the kingdom; and in the beginning of the latter year, it appears that the master and all the brethren of this hospital had fallen victims to the disease, which is stated to have destroyed nine-tenths of the clergy throughout England." How long the hospital may have remained vacant is uncertain; but in 1367, the bishop of Winchester collated to the mastership Thomas de Chesterton; and there was, probably, a regular succession of masters, or priors, until the year 1436; when, as it is alleged, the establishment was so much reduced that the bishop of the diocese procured leave to unite it to the hospital of St. Thomas, in Southwark.

King James the First, in the beginning of his reign, granted the chapel of Sandon to John, earl of Mar; but it was afterwards re-annexed to the manor. No vestiges of the buildings are now to be found.
