The temple of Janus, still standing, was excavated between 2013 and 2018. Its origin could be clarified. It dates back to the Gallic period and to the 3rd century B.C. The antiquity of this sanctuary could be one of the reasons for the choice of the topographic site to establish the new capital of the Aedui, in the Augustan period. The hypothesis of a cult to "Janus" is false. It seems to stem from a misinterpretation of the toponym, "Genetoye", which refers rather to broom. On the other hand, an offering discovered during excavations at the site of the temple mentions the indigenous deity 'Ienieco', who could be one of the gods of the sanctuary. For the moment, this god is only attested in Autun.
The theatre and the baths of the sanctuary have been partially excavated. The Genetoye show building is 116 m in diameter, smaller than the urban theatre, but still large enough to be one of the largest theatres in Gaul.
Finally, the artisanal quarter has benefited from 8 years of excavations. Production was initially focused on metallurgy, but in the 2nd century, it turned to the manufacture of ceramic tableware. More than a hundred potters' kilns have been identified. Figurine workshops have also been discovered, linked to the famous coroplast Pistillus. Some of these products were intended for export, others for consumption within the sanctuary itself.
