Its original elliptical dimensions were 616 feet by 512 feet, with outer walls 164 feet high and a perimeter of 1,788 feet, comprised of three tiers of 80 arches each. The actual arena was a sand-covered wooden floor 250 by 150 feet in size. There were 80 numbered entrances, with four set aside in the cardinal directions for VIPs (the true north entrance for the emperor and his guests). Visitors were given a ticket with entry door, row and seat number and all rows and seats were similarly numbered. The “nosebleed” seats at the top were for the lower classes, but everyone gained free admission and the stands could accommodate 70,000.
