Tolosa: (Greek Τολῶσσα): capital of the Volcae Tectosages in southern Gaul, modern Toulouse.
Purpan and Ancely are the names of two quarters of Toulouse, built on the Lardenne Plateau, which is separated from the main city in the east by the river Garonne and from the countryside in the west by the river Touch.
In the middle of the first century CE, a sanctuary developed in Ancely. It included a temple, public baths, seasonal housing, commercial zones, and numerous wells. Since it was close to the confluence of the Touch and Garonne rivers, the site may have been dedicated to the worship of water. The amphitheater at Purpan was probably erected as an annex to the sanctuary. The complex was abandoned at the very end of the fourth century.
