The Colosseum is a massive elliptical amphitheatre in the center of Rome, built of travertine limestone, tuff, and brick-faced Roman concrete. Commissioned by Emperor Vespasian starting in 72 AD and completed by his successor Titus, it is officially the Flavian Amphitheatre, and it remains the largest standing amphitheatre in the world.
Why it is worth the trip
Standing before the walls, you feel the scale of a structure designed to hold up to 80,000 people for gladiatorial contests, animal hunts, executions, and even mock sea battles. The architecture records generations of work: Vespasian's initial construction, Titus's completion of the top levels, and Domitian's gallery and the hypogeum, a tunnel system that housed animals and gladiators. The name itself likely comes from the Colossus of Nero, a giant bronze statue that once stood nearby. Built on land taken from Nero's private estate, the amphitheatre placed public spectacle at the heart of the city.
The best time to go
Go early in the day, since queues for Rome's most popular attractions can exceed an hour and crowds only build as the morning goes on. Mid-May can bring free admission to government-owned sites during La settimana dei beni culturali, though expect correspondingly heavy crowds. Good Friday evening brings a torchlit Way of the Cross procession starting at the Colosseum, a striking sight if your trip coincides with it.
How long to allow
Allow ample time to explore the different levels and sections of the architecture, since the structure rewards slow looking. Plan on at least a couple of hours inside, more if you combine it with the surrounding ancient sites.
Getting there
The Colosseum sits in the center of Rome, just east of the Roman Forum, within walking distance of the city's historic core. A 3-day Roma Pass, worthwhile if you are staying at least three days, includes entry to the Colosseum and other archaeological sites along with full access to public transport.
What to book ahead
Secure your tickets in advance or choose a pass that grants priority access, as the Roma Pass can often let you bypass queues that run over an hour. Booking ahead also protects your preferred time slot on busy days.
Nearby
The Roman Forum lies just to the east, the civic heart of ancient Rome, and Palatine Hill to the right holds the remains of the Flavian Palace with views toward the Circus Maximus. The Arch of Constantine stands nearby, marking the transition toward the Palatine Hill.
