St. Peter's Square is a massive, historic plaza located in Vatican City. This small papal enclave sits within Rome, Italy. The square is positioned directly in front of St. Peter's Basilica. Both the basilica and the square are named after Saint Peter. Catholics consider him an apostle of Jesus and the first Pope. Today, the square serves as a grand forecourt for the basilica. It is a place where millions of visitors gather to experience religious history.
The square's layout is a complex piece of Baroque architecture. It features a shape known as an ovato tondo. This term describes a shape that is both an oval and a circle. The ovato tondo is 240 metres across. The design creates a trapezoidal entrance to the basilica. This shape provides a heightened perspective for visitors. It also creates a specific sense of movement. The long axis of the oval runs parallel to the basilica's façade. This design provides a pause in the sequence of movement as people approach the church.
Gian Lorenzo Bernini was the architect who gave the square its famous form. He worked on the redesign between 1676 and 1667. He did this under the direction of Pope Alexander VII. Bernini wanted to create a space where the largest number of people could see the Pope. He specifically designed it so people could watch the Pope give blessings. This might happen from the middle of the basilica's façade. It might also happen from a window in the Vatican Palace. Bernini used a style called the Tuscan order for the colonnades. He chose this to avoid competing with the palace-like façade designed by Carlo Maderno. However, he built them on a colossal scale to inspire awe.
The most striking feature of the square is the massive colonnades.
At the very center of the square stands the Vatican obelisk. 
The square also contains beautiful water features and unique paving. Two large granite fountains sit in the space. One was designed by Carlo Maderno in 1613. Bernini matched this by building a second fountain in 1675. The paving uses travertine to create radiating lines. This design helps prevent the ground from looking like a plain sea of setts. In 1817, the paving became even more functional. Circular stones were set to mark the tip of the obelisk's shadow at noon. As the sun moved through the signs of the zodiac, the obelisk acted like a giant sundial's gnomon.
Modern history has changed how people approach the square. The Via della Conciliazione is the grand road leading to the site. This road was created following the Lateran Treaty of 1929. Before this, a section called the spina divided the roads. This spina was demolished between 1936 and 1937. This demolition removed an important medieval and Renaissance quarter. It also removed the "Baroque surprise" of moving from a narrow space to a large one. Today, the square is subject to Italian police for crowd control. However, the Lateran Treaty states that Italian authorities must withdraw during special Holy See functions. This ensures the square remains a sacred and organized space for the world.
