What to See and Do

St. Peter’s Square is one of the biggest and most beautiful ones in the world. Here’s everything you shouldn’t miss:

The Shape and the Paving

St Peter’s Square is quite unique because it consists of two different shaped parts: the main body of the piazza, which is elliptical, and the trapezoidal section in front of the basilica. 

Bernini designed the trapezoidal section out of necessity because he lacked space, but today it’s considered a “masterpiece of the Baroque theatre” because it creates a heightened perspective for visitors leaving the basilica.

The square, which is paved out of cobblestones (like most of Rome), is also decorated with lines of white travertine in a geometric pattern, giving the piazza a harmonic look.

Years later, stones inscribed with the zodiac signs were added around the base of the obelisk, turning it into a sundial’s gnomon. At noon, the shadow marks the current zodiac sign.

The Obelisk

The centerpiece of the square is an Ancient Egyptian obelisk brought to Rome in the year 37 CE by Emperor Caligula. Initially placed at the Center of the Circus of Nero, it was moved to its current location in 1586 by orders of Pope Sixtus V.

The obelisk was actually moved to the Vatican almost one hundred years before the current square was built. So, rather than the obelisk being placed on Bernini’s piazza, Bernini’s piazza was designed around the obelisk.

The Fountains

On either side of the obelisk sit two large fountains. The first also preceded the square and was built by architect Carlo Maderno. It has an octagonal base, a large basin, and a mushroom-like cap from which spouts the water. It was built on top of a restored aqueduct.

The other fountain, built by Bernini years later, was designed to resemble its companion in order to make the piazza look symmetrical, though it’s very different from Bernini’s usual elaborate style.

The Colonnades

The colonnades are arguably the square’s most impressive feature. Built around the elliptical shape of the piazza, the colonnades are four rows deep and built on a massive scale. Bernini purposely chose to use the most simple style, the Doric order, so that the columns wouldn’t clash with the more elaborate ones on the facade of the basilica.

Topping the colonnades are 140 larger-than-life statues. They represent various Saints and Martyrs and took over ten years to complete.

The colonnades were designed to look welcoming. According to the architect who designed them, Bernini, they were meant to embrace visitors into the “maternal arms of the Church”.

St. Peter’s Basilica

No visit to St. Peter’s Square is complete without a visit to the basilica it was designed for. St. Peter’s Basilica is not only the largest church in the world, but it’s also the headquarters of the Roman Catholic Church.

Although the building itself is an incredible work of art in its own right, the inside is also filled with artistic and architectural masterpieces by artists such as Raphael and Michelangelo. 

If you’re at the piazza at Easter, Christmas, or occasionally on Wednesday mornings, you may even get to see the Pope waving from the balcony of the facade.
