The Roman Colosseum had 80 entrances at ground level.
The enormous Flavian amphitheatre was designed to move tens of thousands of spectators efficiently. Of its 80 entrances, 76 were numbered and used by ordinary members of the public. Tickets indicated the appropriate entrance, helping visitors reach their assigned seating sections through a network of corridors and stairways.
The remaining four entrances were positioned on the main axes of the elliptical building and were reserved for privileged users, including the emperor, political authorities, religious officials, and performers. These axial entrances were not numbered like the public entrances.
The Colosseum was built under Emperor Vespasian beginning around AD 70–72 and completed by his son Titus in AD 80. Its entrance system was a major feat of Roman crowd management. The Latin term vomitoria refers to passageways that rapidly dispersed spectators; it does not mean that the Colosseum contained rooms for vomiting.
