Rome's newest tourist attraction opened to the public last week. And as with so many sites worth seeing in this ancient city, it's actually not new at all.
For centuries a huge muddy field, the spot known as Circus Maximus was once used as a stadium for chariot races, religious ceremonies, processions, and other big public events in the days of ancient Rome.
Six years of excavations have turned the site into an archaeological ruin where you can see very old latrines, what remains of a triumphal arch, and equine artifacts recovered from the dig. Climb a restored medieval tower for a better view of the scene.
