A brief history

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.
