I laughed imagining myself as a smuggler delivering “contraband booty” of cat-themed potholders. Not to sell, well, not for me, anyway. These were for a special non-profit organization. Underground, sort of, but completely legit. The Largo del Torre Argentina contains the “Area Sacra,” an expansive ruin that was built on top of the senate building where Caesar was assassinated. The top layer of ruins lay at a good 4-5 meters below the surrounding street level.
