"Caput Mundi" in Rome, 2012

A very, very interesting exhibit on the Ancient Roman Empire inside the Coliseum.  

Two birds with one stone as you could catch the exhibit (which also showed the elevator system used in the ancient amphitheater to bring up both animals and the gladiators on the surface) and the old Coliseum itself, site of that TRULY memorable concert by Sir Paul McCartney on May 10^th, 2003 (both INDISE and OUTSIDE the ancient arena)!
