L’Arco di Costantino di Roma celebrates the triumph of Emperor Constantine over Maxentius, which took place on October 28, 312 AD following the Battle of the Milvian Bridge. As can be inferred from the inscription placed above the central arch, the monument was solemnly dedicated by the Senate to the emperor in memory of that triumph and on the occasion of the Empire’s decennalia at the beginning of the tenth year of reign on July 25, 315 AD.
The monument, included in the fortress of the Frangipane family in the mid-12th century, underwent restorations and studies from the late 15th century throughout the 16th century, but the most significant intervention dates back to 1733, when extensive additions were made to the missing parts.
