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
