"The structure of the chapel, built in a great hurry in the 1470s, had given trouble from the start, with frequent cracks appearing. At Christmas in 1525 a Swiss Guard was killed when entering the chapel with the pope when the stone lintel to the doorway split and fell on him. The site is on sandy soil, draining a large area, and the preceding "Great Chapel" had had similar problems."
