Fortified and enlarged in 1280 by Philippe de Savoie, it constituted a major strategic position facing the Dauphiné during the Dauphiné-Savoy wars. Abandoned in the 17th century, the estate was rehabilitated from 1969 by volunteers. The municipality has owned it since 1992. The site reveals an imposing circular keep, a chapel, ruined residential buildings and its fortified courtyards. Perched on the Relong hill, this historic site offers an exceptional panorama that extends to Lyon. It is also famous for having served as the setting for the very first episodes of the cult series Kaamelott by Alexandre Astier.

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
