Alesia was an oppidum of the Celtic Mandubii in present-day Burgundy. A dedication to the gods alludes to the presence of a shrine at the curative spring, where sick pilgrims could bathe in a sacred pool. The sanctuary itself, located near the eastern gate of the town just outside the city wall, was impressive, with baths and a temple. In addition, there were porticoes, where the sick possibly slept, hoping for divine visions and cures.
Numerous votive objects were dedicated to Moritasgus. These were models of the pilgrims and the afflicted parts of their bodies: these included limbs, internal organs, genitals, breasts, and eyes. Surgeons' tools have also been found, suggesting that the priests also acted as surgeons.
The name Moritasgus, shared by a 1st-century BC ruler of the Senones, has been analyzed variously. It probably means "Great Badger" or "Sea Badger." The European badger produced a secretion used in Gaulish medicaments, hence a possible connection with a healing god.
