Piazza San Silvestro is a square in the center of Rome. It is named for the Basilica of San Silvestro in Capite facing it and that was built on top of the house of two brothers who both became Pope, Stefano II and Paolo II. It used to be a major bus hub, but has now been transformed into a pedestrian area.

History

During the late Middle Ages the square was called Catapauli for a while, a semi-Greek, semi-Latin word meaning “near Paul”.
The site where Piazza San Silvestro is located used to be the location of the Temple of the Sun (Tempio del Sole), which had been constructed by Aureliano in 273, after the conquest of Palmira. The temple consisted of two courtyards connected by a square room. One of the courtyards featured a round temple with 16 columns. Underneath the surrounding arches the vina fiscalia, wine that was to be distributed for free, was preserved.
From the 1940’s until 2011 the Piazza San Silvestro was a major bus hub.
