The St-Bonnet chapel, whose first vestiges could date from the 11th century, was then the center of a parish, but its importance quickly diminished. At the base of the walls of this chapel, large blocks of white limestone are quickly noticed in re-use. These blocks come, after crossing the Rhône, from the important Roman quarry of 'choin'(*) of Fay, located in the Ain towards Murs and Géligneux. They have been worked and have sealing holes. These are probably the remains of a structure intended to cross the Bionne (Biaume by its old name or Belna if one refers to the charters of the Temple of Vaulx) on the Roman road which, starting from Vienne, via Bourgoin and Aoste sur Guiers, reached Geneva. https://www.roche38.fr/copie-de-la-pierre-marquee

This neo-Romanesque church was rebuilt in 1900 to replace the previous one which was destroyed during the Revolution. The church is made up of a nave and aisles of three bays, a polygonal chevet and a bell tower on the front.

Superb point of view, orientation table. Big raidar over 20m to get there: tough but doable by muscular mountain bike. OK in e-MTB turbo mode!
