Climbing the staircase in the south transept

We are in the chapel of the Conversion of Saint Paul. Cunningly hidden behind the 18th-century wooden paneling is the door to a circular staircase. We enter the dark space of the stairs and climb, admiring the extraordinary control over the shaping of the stones that form the steps and the newel post at the center. In passing from the light of the chapel to the darkness of the stairs we mimic the episode of the blindness of Saint Paul.
