Largo di Torre Argentina is an archaeological site in Rome containing the remains of four Republican-era temples and the ruins of Pompey's Theatre. The site is historically significant as the confirmed location of Julius Caesar's assassination at the Curia of Pompey. Below street level, the ruins serve as a managed sanctuary for a colony of feral cats, cared for by a volunteer organization. Recent restoration projects, concluded in 2023, introduced elevated walkways that allow visitors to view the ruins from within the archaeological footprint. The site spans a complex chronological period, with layers of structures dating from the 4th to 2nd century BC. It remains one of the most visible examples of ancient Roman layers integrated into the modern urban fabric of the city.
