A busy transport hub, the Largo di Torre Argentina is set around the sunken Area Sacra and the remains of four Republican-era temples, all built between the 2nd and 4th centuries BC. These ruins, which are among the oldest in the city, are out of bounds to humans but home to a thriving population of around 250 stray cats and a volunteer-run cat sanctuary.

On the piazza’s western flank, Teatro Argentina, Rome’s premier theatre, stands near the spot where Julius Caesar was assassinated in 44 BC.
