Small isolated building in the place called Villieu (former islet in the heart of the Bourgoin marshes), consisting of a small nave lit by a bay on each side and extended by an apse with a lower height than the nave. The facade is pierced by an entrance door surmounted by a basket-handle lintel bearing the inscription 1893 / NOTRE DAME DE VILLEU. https://recensement.patrimoine-religieux.fr/eglises_edifices/38-Isere/38415-Saint-Marcel-Bel-Accueil/150630-ChapelledeVillieu

Beautiful cycle path, mostly shaded, unpaved but rideable (I ride it with 23mm tires), which follows the old line of the Chemin de Fer de l'Est Lyonnais (CFEL)

Nice Sunday morning Gravel ride. Arrived at 8 am in Miribel park, not a soul 🐈⬛ but a few hares and signs waking up quietly near the many beaches. I'm surprised by the quality of the singles and trails which are super well maintained. Would gladly do it again.
