In 1512, in the face of the extreme poverty of the monks (they even lacked priestly robes), the Pope Julius II transformed the priory into a parish. In 1534, Geneva was shaken by the fights of the Reformation. The partisans of Catholicism fled the city and took refuge in the castle of Peney, from which they launched attacks against the Republic, pillaging and robbing the region. They are called the “Peneysans”. The Bernese troops took over the castle on the 5th of February 1536 and finally demolished it.
