Founded before 1125, St Leonard's Hospital was a leper (or lazar) house supported through almsgiving by Peterborough Abbey. Leprosy was particularly prevalent at this time though such houses also provided for other categories of ill and destitute people. St Leonard’s became known as “The Spital”,Spital was a Middle English term used to describe a hospital or its endowed land.
It was still in existence in the 16th century and is assumed to have closed at the time of the dissolution of the monastery.
It was probably located close to the northern end of Peterborough railway station with its own cemetery to the west which is likely to have housed some of those who died from the plague. It gave its name to St Leonard’s Street which was the section of Bourges Boulevard which now runs past the station.
Associated with the hospital was a healing spring or well which was still documented in the mid 17th century.
