Overview

Saint Peter's Square is a grand elliptical plaza designed by Gian Lorenzo Bernini, situated directly in front of Saint Peter's Basilica. The square is enclosed by two semicircular colonnades composed of 284 Doric columns and 88 pilasters arranged in four rows. At the center of the piazza stands a 25-meter-tall Egyptian obelisk, transported to Rome by Emperor Caligula and moved to its current location in 1586. The paving features a wind rose or compass, marked by marble discs indicating the primary wind directions. Two identical fountains, one by Carlo Maderno and the other by Bernini, sit on either side of the central axis. The square marks the physical and spiritual entry point to Vatican City, serving as the primary gathering space for papal events and religious ceremonies. The open design creates a symbolic embrace for pilgrims and tourists entering the Basilica.

Insider tips

• Stand on the two circular marble stones near the fountains to observe the optical illusion where the four-column rows converge.

• Check the Vatican's official calendar for papal appearances, as the square becomes restricted and exceptionally crowded during these events.
