Surrounded by limestone cliffs, Lake Peiroou is an artificial lake, with a capacity of 80 000 m3, retained by a dam. Its name comes from the Provençal "pèiroù" which means cauldron. It was here that the Romans built a dam that supplied water to the city of Glanum, thanks to an aqueduct. It was one of the first "arch dam" of history. The current dam, meanwhile, was built in October 1891, in the same place as that of the Romans, to supply the fountains of Saint-Rémy-de-Provence.
