St. Peter's Basilica is free to enter and is the largest church in the world by interior volume, built over what's traditionally held to be the burial site of St. Peter. Expect airport-style security, a queue on the square that usually moves faster than it looks, and a strict dress code — plan 45–75 minutes for the interior.
The original basilica was built under Emperor Constantine in the 4th century. The building visitors see
today replaced it, constructed between 1506 and 1626 under a succession of Renaissance and Baroque
architects, including Bramante, Michelangelo (who designed the dome) and Carlo Maderno, with Gian Lorenzo
Bernini later adding the piazza's colonnade and the bronze baldachin over the papal altar.
What to see inside
Michelangelo's Pietà, near the entrance, behind protective glass
Bernini's bronze baldachin, towering over the papal altar
The Vatican Grottoes beneath the floor, holding the tombs of many popes
Security and the queue
Expect an airport-style security check before entering the square's queue — it looks long but usually
moves at a reasonable pace, especially early in the morning.
The Basilica has its own entrance, separate from the Vatican Museums — budget a 10–15 minute walk
between the two.
No — entry is free, though you'll go through an airport-style security check and a queue on the square.
Is the Basilica connected to the Vatican Museums?
No — they have separate entrances and separate queues; budget time to walk between them.
How long does the security queue for St. Peter's Basilica usually take?
It varies widely by time of day, often 20–45 minutes at busy periods — going early morning or during the Wednesday Papal Audience, when many visitors are elsewhere, tends to move faster.
