Built by a silk industrialist from Lyon in the second half of the 19th century, the Saint-Siméon-de-Bressieux factory comprises two parts connected by a glass roof. Adjacent to the factory, a large pisé building housed the accommodation for the workers who, coming from afar, lodged on site during the week. This silk mill, established in a rural setting, provided work for nearly 1,000 employees. It operated until 1934. https://www.alpes-isere.com/itineraire/de-soieries-en-chateaux-5335632/ https://patrimoine.auvergnerhonealpes.fr/dossier/IA38000981

Built by a silk industrialist from Lyon in the second half of the 19th century, the Saint-Siméon-de-Bressieux factory has two parts linked together by a glass roof. Adjoining the factory, a large adobe building housed workers who, coming from very far away, stayed on site during the week.

The former abbey church of Saint-Antoine was built in the 14th century on the site of a previous Romanesque church. With its dimensions of 61 meters long, 32 meters wide and a 22 meter high nave, it is on a par with the great Gothic cathedrals. In 1840, the church of the Abbey of Saint-Antoine-l'Abbaye, the mother monastery of the Antoniter order, was included in the list of monuments (Base Mérimée) in France as a monument historique.
