Set in a wall of the former choir, the spiral staircase was a reference for architects of the Middle Ages, and the observation of its vaults is still an essential stage in the training of stone carvers. The vaults’ distinctive construction techniques prove the exceptional know-how of medieval craftsmen. The entrance of the staircase provides an overall view of the former choir.
