A small and relatively unknown archaeological site of ancient Rome, the Largo di Torre Argentina is a square set around the sunken Area Sacra. The remains of four temples built between the 2nd and 4th centuries BC are some of the oldest ruins in the city. What’s left of the Republican-era structures was only just discovered in the 1920s due to construction in the area. The remains of the Theater of Pompey were also found here, said to be the site of Julius Caesar’s assassination.
The four temples are distinguished by letters A, B, C, and D, with temple D being the oldest (it is estimated the columns date back to the 2nd century BC.) They’re off limits to humans — however, the piazza has become somewhat of a cat sanctuary. There are nearly 300 stray cats that stay there, lounging on ancient platforms and strolling among history. The area is maintained by volunteers. Sidewalks surrounding the ruins lead to viewing platforms where visitors are welcome to interact with the cats.
The square is located on Via di Torre Argentina, just to the west of the Teatro Argentina. Multiple bus lines run to the Largo di Torre Argentina stop. The cat sanctuary can be visited daily from 12 to 6 pm. It is free, though donations are accepted.
