Chirens: Priory, Fortifications and Wetland

Key themes for a trip to Chirens include the Romanesque Prieuré de Chirens, medieval fortifications and the Marais du Val d’Ainan wetland. If you’re looking for a hotel in Chirens, these distinctions can help you decide what to focus on: would you like to explore Romanesque art, medieval architecture or nature and habitats?

Nature in the Marais du Val d’Ainan

The Marais du Val d’Ainan near Chirens is an important breeding ground for migratory birds and a habitat for numerous amphibians and remarkable orchids. This natural area is therefore known not only for birdwatching, but also for its diverse wildlife and plant life.

A 1,800-metre-long themed trail allows visitors to explore the area independently and with their families. Its length and the freedom to explore independently provide a clear framework for discovering nature. The Les marais de Chirens circular trail is marked in yellow; signposts at the main intersections help visitors find their way.

Romanesque priory and summer culture

The Prieuré de Chirens is an 11th-century Romanesque priory, decorated with frescoes, classified as a Monument historique and open to visitors. Those interested in medieval architecture will find a tangible combination of architectural history, wall paintings and heritage status here. The frescoes add an artistic dimension to the architectural experience.

The priory’s cultural role is also part of its history. The artist Roger Lorin restored it in 1964; since then, it has been dedicated to the visual arts and music. Every summer, the Prieuré welcomes musicians and visual artists. This summer activity complements the architecture with a cultural focus that is especially interesting for a trip at this time of year.

Fortifications and medieval architectural history

The Le Châtelard fortification was added to the inventory of historic monuments in 2004. The year refers to its inclusion in the inventory, not to when the fortification was built. Maintained paths at the site allow visitors to explore the fortification freely.

The Tour de Clermont in Chirens has a long architectural history: in the 11th century, it began as a simple wooden tower on a medieval motte. From the 12th century onwards, the castle became a stone fortress and the tower its keep. The sequence from wooden tower to stone fortress makes the different stages in the site’s development easy to follow. A keep is the fortified tower of a castle.

Near Lac de Paladru, the Tour de Clermont is one of the last surviving traces of a medieval castle in the Pays Voironnais; it also displays features of the earliest keeps of this period. The architectural history of a single site thus leads to the broader story of medieval castles in the region.

The Tour de Clermont can be reached on foot from Charavines, over a distance of just over four kilometres. If Charavines is your starting point, this gives you a clear idea of the distance to walk.
