Arch of Carpentras, Roman triumphal arch in Carpentras, France

The Arch of Carpentras is a Roman triumphal arch about 10 meters high, 7.8 meters wide and 4.53 meters deep, with a single round-headed opening framed by fluted pilasters. Its lateral faces carry reliefs of trophies flanked by bound captives, and it stands against Saint-Siffrein Cathedral.

The arch was built in the first century CE as the entrance to the Roman forum of Colonia Julia Meminorum, later called Forum Neronis. In the 17th century, it became integrated into the town's structures and gained protection from deterioration.

The side faces display military trophies with two captives wearing different garments, representing peoples from the East and the North. These carvings show how the Romans presented their power over different regions.

The monument sits in the town center and is easily reached on foot, though exact access may vary depending on local rules. It is best explored together with the nearby historical buildings in the area.

The arch was long built into the former episcopal palace, now the courthouse, and 19th-century records show it formed part of the palace kitchen before being freed from later construction. In 1879 an amateur archaeologist proposed selling and moving it to the national archaeology museum at Saint-Germain-en-Laye, but only casts of its faces were made.
