Arco di Costantino (Arch of Constantine), Rome

The Arch of Constantine is one of the most outstanding and well-preserved examples of Roman architecture. Erected in the early 4th century AD, it is a testament to the grandeur of the Roman Empire and a significant monument in the historical narrative of the city.

Situated between the Colosseum and the Palatine Hill, the Arch of Constantine was constructed to commemorate Emperor Constantine's victory over Maxentius at the Battle of Milvian Bridge in 312 AD, a turning point in Roman history that led to Constantine becoming the sole ruler of the Western Roman Empire.

The Arch of Constantine is the largest of the triumphal arches in Rome, standing about 69 feet tall and 85 feet wide. It is the last triumphal Arch erected in Rome and, arguably, the most beautiful of them all. It is decorated with an array of intricate sculptures and reliefs, many of which were repurposed from earlier monuments. These carvings depict scenes from Constantine's military campaigns, as well as from the campaigns of other notable emperors, demonstrating the might and power of the Roman Empire.

One notable feature of the Arch is the inscription dedicated to Constantine, which credits him with saving the Roman people by divine inspiration. This refers to Constantine's vision before the Battle of Milvian Bridge, where he claimed to have seen a cross in the sky and heard the words "In this sign, you will conquer." This event is often linked to Constantine's promotion of Christianity within the Roman Empire.

Standing amid the public road once used as the triumphant passage into the city taken by emperors, the Arch is free to access. Although fenced off, it is well visible from the outside, any time, day or night.
