Choir of St. Saviour's, Southwark
It is the mother church of the Anglican Diocese of Southwark. It has been a place of Christian worship for over 1,000 years, but a cathedral only since 1905. Henry Cardinal Beaufort repaired the church after a 1212 fire. The main structure of the present church was built between 1220 and 1420, making it the first Gothic church in London. Heresy trials occurred in the Galilee chapel in 1555, under Mary I of England.
