Exit or pass the Armoury and you will find yourself in the Angel’s Courtyard. Facing the statue of the archangel Michael, please take the stairs on your left following the official itinerary. At the top of the stairs, you will see a Bar on your left, but to follow the touring itinerary, you need to turn right and walk along the loggia di Paolo III. You will be immediately directed to go up the stairs after seeing the sign for the library. The Loggia is the entrance to the private rooms of Pope Paul III Farnese. Take the staircase, which is just on your right to enter the rooms. The first one is the Library (official numbering 13 or official audioguide no.10).
