At the side of the organ in the south transept [of the Church of St Cross], traces of wall paintings in a tomb recess are the last remains of what was once an altar to St Thomas of Canterbury, the martyred archbishop. A nearby door was where travellers coming from the continent to Canterbury arrived. It would also have been the point of departure for crusaders. Knights of St John would spend their last night praying here before embarking at Southampton for the Holy Land.*
