St Oswald's Priory, Gloucester, Gloucestershire
These are the ruins of the former Augustinian Priory of St Oswald. It was founded by St Athelflaed in c900. Major changes were made to it in the 12th and 13th centuries. After the dissolution (c1536) the priory was largely demolished except for the aisle. This was converted for use as the parish church of St Catherine.
