Château d'Irigny

The Château d'Irigny is a castle featuring two prominent towers connected by residential sections that reveal medieval construction techniques. The structures preserve remains of defensive features, including traces of the former moat that once surrounded the buildings.

Construction began between 1193 and 1226 under Renaud de Forez, Archbishop of Lyon, establishing the fortress in the region. In the 14th century, damage from a group called the Tard-Venus led to partial destruction, yet the structure was gradually restored and remained occupied.

The Croppet family coat of arms is displayed on the facade, featuring gold and three blue cinquefoils that mark their long connection to this place. This heraldic symbol reveals something of the noble families whose names were linked to the region for generations.

The building now serves as the municipal library of Irigny, located at Place de l'Église in the town center, offering access to books and local collections. Its central location makes it straightforward to visit and view the medieval structure while using the library's resources.

A 14th-century assault by a group called the Tard-Venus damaged much of the fortress, yet it retained enough structural integrity to survive and remain standing. This resilience demonstrates how solidly medieval fortifications were built and their ability to recover from wartime destruction.
