The Priory or Hospital of St Thomas of Canterbury was a house of Augustinian canons in medieval Birmingham. The institution is referred to in sources as either a priory or a hospital, but the two roles were often overlapping or interchangeable during the medieval period, as all monastic institutions were supposed to care for the poor, sick and itinerant. The priory was situated north of Bull Street - then called Chapel Street after the priory's chapel of St Mary - in an extensive tract of its own land that extended as far as the Prior's rabbit warren or conygre, now marked by Congreve Street near Chamberlain Square. The date of the priory's foundation is unknown, but numerous later records suggest that it was established by a member of the de Birmingham family.
The first record of the priory occurs in 1286, when gifts of property from three local land-owners were licensed to be held in mortmain; and a pardon issued in 1310 for the failure to similarly license thirty-three other donations of land suggests that the priory was thriving at this time. In 1344, however, its management was severely criticised by a visitation, and it was extensively reformed by the Bishop of Lichfield. This seems to have been effective and resulted in a further series of endowments, including the establishment of a chantry in its chapel.
