About Thermes de Constantin
The Thermes de Constantin, also called the North baths, are 4th-century Roman public baths built on the banks of the Ródano in the time of Emperor Constantine, who spent seasons in Arles. The Roman city had three bathing establishments; this is the best-preserved one.
What you see today is the caldarium area, the hot-bath room, with a semicircular apse of brick and stone. Under the floor lie the pillars of the hypocaust, the system that circulated hot air beneath the floor to heat the rooms. Parts of the tepidarium, the warm room, also survive.
Panels explain how a Roman bath worked: inhabitants moved through the cold, warm and hot rooms, and the baths were also a meeting and social place. The site is small and the visit is quick.
The baths are part of the Arles ensemble listed by the Unesco and sit next to the Fondation Vincent van Gogh and the Musée Réattu, an art museum, on the quay.
