The Arch of Constantine (Arco di Costantino in Italian) is the largest triumphal Roman arch. It’s situated near the Colosseum and it was built in 315 AD to commemorate Constantine I’s victory over Maxentius at the Battle of Milvian Bridge. In ancient Rome, the troops and the emperors used to enter the city in triumph passing under this arch.
Even though it’s dedicated to Constantine, the decorations also represent previous emperors’ victories. In fact, Trajan, Hadrian, and Marcus Aurelius are also part of the arch’s low relievs.
Nowadays, the Arch of Costantine is one of the major attractions in Rome. It’s totally free, since it’s outdoor, and you can visit it anytime.
