There is something unnerving yet compelling about exploring crypts and vaults. If this sounds interesting to you, stop by Augustus Mausoleum.
Sometimes it's the places that don't cost a thing that end up making some of the best travel memories. And you'll likely make a few at this free tomb site in Rione IV Campo Marzio. When you're done at Augustus Mausoleum, also check out St. Peters Basilica, Roman Forum and Piazza Navona.
