Basilica of Saint Paul Outside the Walls
In 979, the Count of Seprio, Amitto (Amizzone), captain of Otto I, transferred Felinus' and Gratian's relics, with the permission of the bishop, to Arona, and built a monastery dedicated to them. Amitto's foundation has been interpreted as a form of penance, since his soldiers had set fire to the portico of the basilica of Basilica of Saint Paul Outside the Walls.
