Condat Abbey was founded in the 420s in the valley of Bienne, in the Jura mountains, in modern-day France. Condat became the capital of Haut Jura. The founders were local monks, Romanus (died c. 463), who had been ordained by St. Hilary of Arles in 444, and his younger brother Lupicinus of Lyon (Lupicin); the easily defended isolated site they chose for the separate cells in which they and their followers would live in emulation of the Eastern manner of the Desert Fathers was on a stony headland at the confluence of the rivers Bienne and Tacon. Though the site still contained Roman ruins, it was accounted a 'desert' in the Life of the Fathers of the Jura, which contains the early saint's lives. Romanus continued founding other abbeys, such as Romainmôtier Abbey at Romainmôtier-Envy, which retains his name.
