 This arena is where Spartucus ended up before he escaped to form an army. This whole area was where the military was based for ancient Rome...training grounds and barracks. I arrived on a Sunday night and ran to get to it. I left my phone behind...It was late. I could have gotten in had I had my C pass....that is in my phone! hell...too far to run back...and then it is closed on Mondays...I got to see it from the outside.
