Introduction to the Holy Steps: The Holy Steps (Scala Santa) are the ruins of the Latrano Palace, with a total of 28 levels. It is said that Christ entered Pilate's house from this way during his trial, and it is also said that these steps were brought here from Jerusalem by Constantine's mother. In Catholicism, you can get plenary indulgence by climbing up the holy steps with your knees, so a large number of believers come to confess all year round. (Free, opening hours 6:15-12:00, 15:30-18:45; earlier to 15:00 in winter)
