Medieval origins (11th - 12th centuries): The religious site is of very ancient origin. From the end of the 11th century, several religious buildings are mentioned in the commune. The Saint-Pierre church itself is cited under the name "ecclesia de Anos" in the famous cartulary of Saint Hugues (Bishop of Grenoble). In the Middle Ages, the church was directly dependent on the priory of Saint-Laurent of Grenoble, as attested by an official terrier dating from 1497 under the name "ecclesia Sancti Petri de Fortaressia".

Soierie de Bressieux (officially known as the Girodon factory-boarding school) is a former 19th-century silk weaving mill located in Saint-Siméon-de-Bressieux in Isère, built between 1873 and 1875 by Lyon industrialists and active until 1934.

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.

Departure from the Col des Aures at 13% but on a short portion. Then aerial road with a very nice view, very little traffic and with a good coating.

There is a small cafe, a free water point and a small picnic area in the sun.

A fairly steady climb from Vinay, the start has easier grades of 2-4% with the second and final part increasing to 5-6%. The views from the top are definitely worth the effort!
