The hospital was founded by
Roger de Beaumont, 2nd Earl of Warwick, in the vicinity of a church of the same name towards the end of the reign of
Henry I of England, in about 1135. The warden was a priest. In the 15th century the chapel was probably rebuilt after its parish was merged with the
Collegiate Church of St Mary, Warwick. The half-timbered, two-storey Master's House was also constructed around this time. In 1978 the then owner of
Warwick Castle renovated the chapel had plans to move the buildings to the castle site but this was never realized. The structural problems of the surviving Master's House mean that it is listed on
Historic England's
Heritage at Risk Register as 'very bad'. In 2018 it was announced that after lying unused and covered up for "almost four decades" £530,000 would be allocated to the site to use it for
supported housing, preserving the older buildings in their current condition as best as possible. On January 15 2021, Warwick District Council announced a Compulsory Purchase Order had been served on the owner of the site of the hospital to enable the scheme to proceed. On 13 July 2025 it was announced that the buildings would be converted to affordable housing, following the award of a £2.8 million grant from the
National Lottery Heritage Fund. ==Architecture==
