Largo di Torre Argentina (Silver Tower Square), Rome

Largo di Torre Argentina (literally “Silver Tower Square”) is a striking archaeological site in the heart of Rome’s ancient Field of Mars. This large open space contains the remains of four Roman Republican temples, dating from the 4th to 2nd centuries BC, as well as part of Pompey’s Theatre complex. Historically, the square was also a hub for the argentarii-Rome’s money men and bankers-who conducted their business here. The name itself comes from a Renaissance-era tower built in the 16th century and linked to Strasbourg, once called Argentoratum in Latin.

Perhaps the most famous event tied to Silver Tower Square is the assassination of Julius Caesar. In 44 BC, the Roman Senate was temporarily meeting in the Senate House of Pompey, a hall attached to Pompey’s grand theater complex, because restoration work was being done on the regular Senate House in the Forum. It was here, on the March 15, that Caesar was surrounded by a group of senators-many of them former allies-who feared he had grown too powerful and sought to restore the Republic by ending his rule.

Led by Brutus, Cassius, and other conspirators, they stabbed him twenty-three times. Ancient sources describe Caesar initially trying to resist, but when he saw Brutus among the attackers, he is said to have drawn his toga over his head in despair. The very spot where this dramatic and world-changing event occurred is now marked within the ruins of the square, offering visitors a rare chance to stand at the place where the course of Roman history was forever altered.

The four temples of the square, labeled A through D by archaeologists, provide insight into the religious life of the Republic. Though only fragments remain, including columns, altars, and stairways, they allow a glimpse of the grandeur that once filled the Field of Mars. These sanctuaries were central to Rome’s civic and spiritual life, and today they remain a rare cluster of Republican architecture visible in the modern cityscape.

Adding to its unique appeal, Silver Tower Square is also home to Rome’s most beloved cat sanctuary. Since the 1990s, volunteers have cared for hundreds of stray and abandoned cats who now roam freely among the ancient stones. Tourists often find themselves just as enchanted by the sight of cats lounging on marble blocks as they are by the history of Caesar’s assassination. This unusual coexistence of archaeology and animal rescue makes Largo di Torre Argentina one of the most memorable stops in Rome.
