The Arch of Arcadius, Honorius and Theodosius (Latin: Arcus Arcadii Honorii et Theodosii) was an ancient triumphal arch in ancient Rome.
It was built by the senate in 405 AD after Stilicho's victory in the Battle of Pollentia three years earlier. As per tradition, the victory over the Goths was ascribed to the reigning emperors: Arcadius, Honorius and Theodosius II.
It was near Pons Neronianus and was possibly built right at the bridgehead. It survived until the 15th century, although by then it had been stripped of its marble facing.
