Largo di Torre Argentina is a historic site in Rome, Italy, where Julius Caesar is believed to have been killed and where about 250 stray cats have currently settled as their home.

A site called Largo di Torre Argentina in Rome, Italy, contains the steps where Julius Caesar was killed more than 2,000 years ago; it is also currently home to about 250 stray cats. 
According to Atlas Obscura, the felines moved into the area soon after the ruins were excavated in the late 1920s. 
And, for the past couple of decades, the population has been able to thrive thanks to the caretaking efforts of volunteers. 
In fact, their work led to the eventual formation of the Torre Argentina Cat Sanctuary, a group which is able to give food and medical care to the cats with the help of money received from the public. 
City officials had threatened to close down the operation due to its location at the historic site, but the move was criticized by animal supporters and resisted by the volunteers. 
The sanctuary continues to be a popular destination for visitors.
