Meet your guide just outside the entrance to St. Peter's Square and head past the crowds, straight into the grand Renaissance-era elegance of the basilica.

Next, it's time for a journey through the basilica itself as your guide shows you the grandeur that defines one of the holiest sites in the Catholic world. Admire the exquisite detail of the baldachin designed by Gian Lorenzo Bernini, standing amid the space designed by Michelangelo, and then visit the famous bronze statue of St. Peter with the keys to heaven in his hand. Another special experience is waiting for you beneath the basilica as your guide gives you a rare look at the crypts of the Vatican grotto. With more than 100 tombs holding popes, Catholic monarchs, and famous figures, the crypts let you look back through almost 2,000 years of the church's history. Before you part ways with your guide, they'll lead you to an elevator that carries you to the dome's first terrace. From there, you'll be able to climb St. Peter's dome at your own pace. 320 steps lead you up to one of the best views you can get of the city of Rome—from the square below you all the way across the Tiber.
