The Undercroft Chapel
Beneath the present nave is the undercroft of the Saxon church containing three chapels: the Undercroft Chapel, the Chapel of St Francis of Assisi and the Chapel of St Clare.
This site was formerly outside the main building and part of the burial ground adjacent to the apse of the Saxon church. Here lie at least three Saxon coffins, buried in the pre-Norman period. The rough rear wall is part of the 14th century church.
It was in a vault in this chapel that Archbishop William Laud lay buried for over twenty years after his beheading on 10th January 1644, and a memorial plaque commemorates this.
