St. Peter's Basilica
The Renaissance-style St Peter's Basilica is one of the largest churches in the world (and the home church of the Pope). Highlights include the dome (the biggest in the world), Bernini's Baldacchino (the centerpiece of the church), and Michelangelo's Pietà (the only artwork he ever signed).
For both the pious and the casual visitor, a trip to St. Peter's is an awe-inspiring trip into the heart of Vatican City.
Check ticket availability
We just asked some gentlemen in blue vests where to go in and they personally took us all the way to the check in box. Super fast and convenient. There was at least a 1-2hr waiting line so we were extremely satisfied with the quickness.
