10Free entry for Ancient Romans

Unlike when visiting an arena for a sporting or music event nowadays, entry into the Colosseum was free for ancient Romans.

Not only that, but they got fed throughout the event! It is said that the emperors did this in order to gain popularity throughout the Roman empire. Free entry and food were necessary, because events could last for up to 100 days at the Colosseum. Hours were spent there every day, enjoying the spectacles and catching up with friends.
