Immediately to the south-west of All Saints church on Peasholme Green was the 'Holy Priest's House' where a residence of Chantry Priests and a 'Holy Priest's Well' are believed to have been located (Drake, 1736, 312). This site is marked on the Ordnance Survey map of 1952, on a site that later became a stone yard and a foundry. Raine has examined some thirty York wills to find further information about the house. The foundation is recorded in a will of 1402, by Robert Dawtry, chaplain, who leaves books and vestments to 'Sir William de Coventry, William Swynesheued, John Morele and Robert de Cawood, my fellow chaplains in that place or guest house (hospitium) which Sir Thomas del Spense in the first place and subsequently Thomas Byrkyn, Robert Mayson, deceased and the aforesaid William de Coventry erected and built at great expense at the west end of the church of All Saints Peasholme in York' (Raine, 1955, 85). Raine lists several late fourteenth century wills which include the fraternity of chantry priests amongst the beneficiaries (Raine, 1955, 86). A Visitation of St William's College in 1472 states that each chaplain had a separate chamber (Raine, 1955, 86).
The Holy Priest's Well is noted by Drake and shown on the Ordnance Survey map of 1852. Raine (1955, 87) states that the head of the well was brought to the Yorkshire Museum.
