What to Know Before You Visit Rome's Amphitheatre
Built in a Decade, Standing for Two Millennia
Construction of the Colosseum began around 70 AD under Emperor Vespasian, on the site of Nero artificial lake — a deliberate political act, returning the land to the Roman people. Completed in 80 AD under Titus, it was inaugurated with 100 days of games. At its peak it held an estimated 50,000 to 80,000 spectators, seated by social rank. The engineering — 80 numbered entrance arches, the vomitoria ramp system capable of emptying the building in minutes — was not replicated by Western civilisation for nearly 1,500 years.
What Remains and What You Will See
Roughly two-thirds of the original Colosseum was removed over centuries for building material. From the upper tiers, the structure of the arena is fully readable: the hypogeum — the underground network of tunnels and cages where animals and gladiators waited — is visible below the wooden arena floor, reconstructed in 2023. The Roman Forum and Palatine Hill, both included on the same ticket, extend immediately to the west and deserve at least two hours of their own.
Practical Advice for the Visit
In peak season the ticket queue can be long, in direct sun with little shade. The first slot of the day (usually around 9am) on a weekday is the least crowded; late afternoon (roughly after 3:30pm) is the next best option. Large bags are not allowed inside, so travel light and check the current rules before you go. Arena floor access is a separate ticket that cannot be added at the entrance and sells out early in summer.
