Summary

Triumphal arches originated in the Roman Empire and have been constructed for over two thousand years. These free-standing portals are more accurately known as arch monuments, commemorative arches, or honorific arches due to their diverse functions. Arcuated shapes allow these monuments to span significant roads; multiple façades create space for dedicatory inscriptions, relief sculptures, and statues. Varied reception of this fundamental design concept—a free-standing portal with words and images—is evident in each commemorative arch. Reception of individual arch monuments can be traced through descriptions, representations, and interventions.

The Roman arches dedicated to the emperors Titus (c. 81 ce), Septimius Severus and his sons (c. 203 ce), and Constantine I (315 ce) have strongly influenced the monument’s modern reception, even though they do not represent the monument’s full range of ancient designs and functions. In major European revivals since antiquity, ephemeral arches have adorned political processions, and permanent monuments have commemorated imperial military victories. In the 20th century, arch monuments arose in cities around the globe, often amid debates about national identity.
