Largo di Torre Argentina is a sunken archaeological site in the heart of Rome, where four ancient temple ruins sit below a busy modern piazza. Known simply as Temples A, B, C and D, they date from the Roman Republic and are surrounded by fragments of later buildings. The contrast between the traffic at street level and the columns below is one of the city’s most striking glimpses into its layered past.
The site is also linked to one of ancient Rome’s defining moments. Julius Caesar was assassinated on the Ides of March in 44 BC at the Curia of Pompey, a meeting place associated with the Theatre of Pompey complex beside the temples. The ruins came to light during demolition work in the late 1920s. Today, a cat sanctuary adds a distinctly modern chapter, caring for stray and abandoned cats in the archaeological area.
Largo di Torre Argentina is easy to add to a walk between the Pantheon, Piazza Navona and Campo de’ Fiori. You can see much of the site for free from the street-level railings, or buy a ticket to explore the archaeological area on its raised walkways. Check official opening hours and ticket details before visiting, as access can change. Late afternoon brings warm light to the ruins, while the surrounding streets and transport stops can be busy, so keep an eye on your belongings.
