Why visit
Most people photograph it over their shoulder and keep walking, which is a shame: this is the largest triumphal arch left standing in Rome and the clearest place in the city to see the Empire quoting itself. Panels lifted from earlier emperors' monuments sit beside fourth-century carving, so two very different Romes share the same stone.
History
Dedicated in 315 AD, the arch celebrates Constantine's victory over Maxentius at the Battle of the Milvian Bridge in 312 AD. Much of its sculpture was reused from earlier monuments of Trajan, Hadrian and Marcus Aurelius, which is why it reads like an anthology of three centuries of Roman art.
What to see
The three archways and Corinthian columns, the round Hadrianic medallions, the frieze narrating Constantine's campaign, and the inscription crediting his victory to a divine inspiration.
Anu's local tip
Walk a full circle around it before you leave. The two long faces tell different stories, and the side facing the Palatine is the one almost nobody looks at.
Photo spot
From the Via di San Gregorio side you get the whole arch with the Colosseum behind it and no ticket queue in the frame. Late afternoon light hits the west face and brings out the relief.
Common mistake to avoid
Assuming it is part of the Colosseum visit and only seeing it through a fence from inside. It stands on open public ground, so approach it from the street and take your time.
Nearby
The Colosseum is a minute away, the entrance to the Forum and Palatine a few minutes further up Via Sacra, and Monti is the natural place to stop for coffee afterwards.
Practical tips
It stands on public ground outside the Colosseum, so you can see it without a ticket. The clearest full view is from the Via di San Gregorio side, away from the queues.
Frequently asked questions
Do I need a ticket to see the Arch of Constantine?▾
No. The arch stands on public ground between the Colosseum and the Palatine, so you can walk right up to the railing and study it without any ticket. A ticket is only needed for the enclosed archaeological sites around it.
How long should I spend at the arch?▾
Ten to fifteen minutes is enough to circle it, pick out the reused reliefs and take photographs. It works best as a deliberate pause on the way between the Colosseum and the Forum rather than as a separate outing.
How do I combine it with the Colosseum, Forum and Palatine?▾
The arch sits on the short walk between the Colosseum exit and the entrance to the Forum and Palatine, so it costs you almost no extra time. Stop at it on the way across rather than doubling back for it later.
