Ritona is a Celtic goddess chiefly venerated in the land of the Treveri in what is now Germany. Her cult is attested at Pachten and at Trier, where she "had a carefully built little temple" in the Altbachtal complex. Ritona's temple was one of several in the Altbachtal to include exedrae and courtyards that may have been used to prepare ritual banquets and/or to place offerings. At Pachten her temple also had a theatre, presumably used for performances of a religious nature.
