Hatra was a very impressive place. I was there in 2003 with the 101st airborne. There was a unit there securing the site from looters. The man who was the caretqaker there gave us a tour. I remember walking in to the city itself, the plaza was impressive, there was an arena fairly close to an altar to one of the gods I believe. The main building held the throne room, the court room and a temple. For me it was my first trip into something that old. I loved it.
