The popes always took great care of this path; pope Adrian I (r. 772-95) had more than 12,000 blocks of tufa extracted from the Tiber, widening and repairing the road; Paschal I (r. 817-24) and Leo IV (r. 847-855) carried out restorations after the two terrible fires that devastated Borgo; pope Innocent II (r. 1130-43) renewed the tile roofing of the road.
