The imposing Arch of Constantine was erected in AD 315 to celebrate Emperor Constantine's victory over Maxentius at the Battle of the Milvian Bridge that took place three years earlier. Thanks to its close proximity to the Colosseum and Forum, this ancient monument is included in most ancient Rome walking or Segway tours and shore excursions, and visiting with a guide is the best way to learn about the historic and architectural importance of this massive monument. For a deep dive into Roman architecture, you can opt for a tour of the Arch of Constantine that also includes a visit to the underground portion of the Colosseum along with skip-the-line access to this famous amphitheater, the neighboring Forum, and other highlights of the Palatine Hill. Travelers with kids can choose a family-friendly tour to make these ancient sites more captivating for young visitors.
The Arch of Constantine is located between the Colosseum and Roman Forum at the foot of the Palatine Hill in the center of Rome. The nearest metro station is Colosseo on metro line B.
The arch is located in the center of a small square with little shade next to the Colosseum, so visit in the early morning or late afternoon in the summer to avoid the midday heat and crowds, and on a clear day if visiting in winter.
At 69 feet (21 meters) tall, the Arch of Constantine is the largest triumphal arch in Rome, and the latest of those that still stand in the city. The monument has three arches, and the largest in the center spans the ancient Via Triumphalis, the route used by conquering emperors when returning to the city. The arch is decorated with reliefs taken from second-century monuments that celebrate victories by earlier Roman emperors, as well as inscriptions praising the achievements of Constantine.
