Southwark Cathedral is the oldest cathedral church building in London and was established in 1106 as an Augustinian Priory. From here they ministered to pilgrims and travellers, and to the sick and the needy of the area. As part of their ministry, the Hospital of St Thomas was established.
King’s still maintains its link with the Cathedral through the merge of the United Medical and Dental Schools of Guy's and St Thomas' Hospitals in 1998. This created the School of Medical Education and The Dental Institute and that is why these students still celebrate their Graduation day at the Southwark Cathedral.
