A building for shows
Its first purpose is the obvious one. The Colosseum is an amphitheatre, a ring of seats round an arena, and it was built for the shows that needed one: combats between gladiators, hunts of wild animals (venationes) and contests between men and beasts. When Titus dedicated it in 80 CE, the games lasted a hundred days, and the historian Cassius Dio describes nine thousand animals killed, women taking part in the hunts, and the arena suddenly filled with water for horses, bulls and a naval battle. Gladiatorial games were held here until the emperor Valentinian III abolished them in 438; other spectacles continued to the end of antiquity.
A gift with a message
Its second purpose was political. The amphitheatre stands on what had been the grounds of Nero’s Golden House, in the valley where Nero had made an artificial lake. Vespasian drained the lake and built a public arena there, a choice that was as symbolic as it was practical: the private pleasure of a hated emperor became a place for tens of thousands of Romans. And it was paid for with the spoils of Jerusalem, sacked by Titus in 70 CE. Every show reminded the crowd who had won the war and who was paying for their entertainment.
The emperor was part of the show too. Titus gave the opening games, and later emperors gave theirs: in the Colosseum the people received the shows as gifts from the ruler.
A map of Roman society
Its third purpose was to put everyone in their place, literally. The rules for seating at public shows went back to Augustus: senators in the first row, soldiers separated from civilians, special seats for married men of the common people and for boys with their tutors, and women allowed to watch the gladiators only from the upper seats. The Colosseum built those rules into stone. The nearer you sat to the arena, the higher your rank.
Comfort was managed as well. A huge retractable awning, the velarium, shaded the crowd from the sun; it hung from masts set on stone brackets at the top of the building, and it took hundreds of sailors to work the rigging.
Were Christians martyred here?
It is one of the most repeated stories about the Colosseum. Is it true? The evidence does not settle it: Britannica states plainly that it is uncertain whether the arena was the site of the martyrdom of early Christians. The verdict: not proven.
So what was it for?
Shows, first of all; but shows were never just entertainment in Rome. The Colosseum gave the people their games, gave the Flavian emperors a monument to their generosity on the site of Nero’s luxury, and gave Roman society a seating plan in stone. What happened underneath the arena made the shows possible.
Where to see it
The Colosseum is in the Parco archeologico del Colosseo, in central Rome; entry is by timed ticket, and the underground and arena floor need a special ticket. Prices and opening hours for October 2026 are in the guides to the Colosseum’s dates and to its interior.
