Why go
Its value lies in close comparison. Reliefs reused from monuments of Trajan, Hadrian and Marcus Aurelius sit beside fourth-century carvings made for Constantine, creating visible shifts in scale, modeling and style. The arch also marks the ancient triumphal route between the Circus Maximus, Palatine and Roman Forum.
What to look for
- Compare the reused second-century roundels and attic panels with the Constantinian battle and procession friezes below.
- Read the three archways as part of the ceremonial road followed by imperial triumphs.
- Step back toward the Colosseum side to see how columns, sculpture and the long attic inscription form a single façade.
Useful to know
- Plan 15–20 minutes and include it naturally between the Colosseum and the Palatine entrance.
- The monument is viewed from outside in a busy, fully exposed archaeological zone.
