Rome and its relics: catacombs, crypts and cities of the dead
You’ll notice when visiting Rome that the city proper is free of the massive cemeteries you see in other major cities such as Paris with its well-known and heavily-visited Père Lachaise, Montmartre, and Montparnasse Cemeteries. By law, Romans did not (and still don’t) bury their dead within the city walls, which means you’ll find attractions such as its famous catacombs located outside the city’s boundaries.
