Atop the Dome at Saint Peter’s Basilica From here you have heavenly views above Saint Peter’s square and the welcoming arms of the Bernini colonnades. Just as amazing are the 360 degree view of Rome and the lush Vatican Gardens. From the entrance to the top of the dome, it’s a 320 step climb. If climbing the cupola is not your cup of tea, you can take the elevator to the roof, and greatly shorten the distance. You do need to take the stairs for the final ascent to the top of the dome.
