Standing proud behind the Colosseum and steps away from the beginning of the Via Sacra, the imposing triumphal Arch of Constantine (Arco di Costantino) was erected by the Roma Senate in 315 AD in honor of Emperor Constantine's victory over Maxentius at the Battle of the Milvian Bridge that took place three years earlier. At 69 feet (21 meters) tall, the ornate monument was carved from a single enormous block of gray and white marble. In typical Classical style, the great central gateway is mirrored by two smaller side arches and supported by eight Corinthian columns. The arch is decorated with reliefs plundered from other long-forgotten memorials that describe feats of bravery by earlier Roman emperors, as well as inscriptions praising the achievements of Constantine.
Thanks to its close proximity to the Colosseum and its sheer size, the Arch of Constantine is an easy landmark to find and a popular spot for photos. Many walking tours stop to admire the arch before continuing on to the Colosseum, the Roman Forum or to Palatine Hill.
Located on Via di San Gregorio in Rome, travelers can take the Metro or a taxi to the Colosseum next door.
