When the territory of the municipality formed part of the Peney castellany, the town had a priory devoted to St Peter. A chart from 912, the oldest authentic document in Geneva’s history, notifies the donation by Eldegarde, probably a countess, of part of the assets inherited from her husband to the monastery of St Peter. However, she reserved for herself the usufruct of the lands located in Satigny, Choully, Peissy, Challex, Crest, Logras, and Feigères, and she asked the bishop of Geneva to ensure that her donation was well executed.
