Saint-Siméon-de-Bressieux brings together the history of a silk factory and workers’ community, a wetland area and a range of architectural heritage. There are different ways to explore: learn about the town’s industrial history, look at traditional building methods or plan a visit to the discovery trail at the Tourbière des Planchettes. Information about two circular routes provides a useful guide to how long to allow. For the church and mill, it is advisable to check visiting arrangements in advance.

Silk factory and workers’ town

The Girodon silk factory and workers’ town were listed as historic monuments on 17 July 1990. The present buildings of the Manufacture de soierie et cité ouvrière Girodon were constructed between 1873 and 1875. The complex consists of two sections connected by a central glass roof. In 1875, a workers’ boarding house built of rammed earth was added. When the silk factory opened in the 19th century, Saint-Siméon-de-Bressieux developed into a workers’ community. Alongside production, the boarding house draws attention to the residential role associated with the community.

An older example of local architecture is the Maison en torchis: a former tannery dating from the 17th century, built entirely of earth and timber framing. Traditional building techniques were preserved during its restoration. Compared with the silk factory buildings, it reveals a different construction method and an earlier period in the town’s history.

Wetland landscape and discovery trail

The Tourbière des Planchettes in Saint-Siméon-de-Bressieux is designated an Espace naturel sensible (ENS) and has the site code SL040. Its habitats include marshland, ponds and heathland. The discovery trail leads through the forest to a boardwalk over the wetland. From there, you can observe the wetland at close range. A marked circular trail at the Tourbière takes about two hours. The site’s car park is signposted from Saint-Siméon-de-Bressieux.

Two circular routes, two different focuses

The «De soieries en châteaux» circular route takes in architectural heritage dating from the Middle Ages to the 19th century. It is 6.1 kilometres long, rated moderate and takes about two hours. Yellow markings identify it as «Promenade et Randonnée». The two circular routes therefore take a similar amount of time but have different focuses: «De soieries en châteaux» centres on architectural heritage, while the Tourbière route explores the wetland landscape and its habitats. When planning your outings, you can take into account not only the approximate duration but also the stated length and difficulty of the heritage route.

Church and mill oil

The Eglise St Siméon is open during the day. Check the local opening hours before your visit.

The Moulin Pion Vignon is associated with the production of walnut and hazelnut oil in a traditional watermill. If you are planning a visit, check the current visiting arrangements in advance.
