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
