The largest church in the world, at the heart of the Vatican. Climb the dome early.
St Peter's Basilica is the vast Renaissance church at the centre of the Vatican, Michelangelo's dome, Bernini's baldachin, and a scale that reduces everyone to a whisper. It's free to enter, and the queue proves it.
Yes, and it's free; go at opening and climb the dome, just cover up for the door.
The grounds are free; going inside or up is ticketed โ book online ahead to skip the queue.
Arrive at opening (around 7am) to walk straight in before the security line wraps the square, and climb the dome (cupola) for the best view in Rome, taking the lift partway then the tight, leaning stairs.
