Château de Rajat, Historic castle in Saint-Pierre-de-Chandieu and Heyrieux, France.

Château de Rajat is a castle located in Saint-Pierre-de-Chandieu and Heyrieux near Lyon, straddling two communes in the region. The building features a grand staircase, arched windows, and sits within landscaped gardens dotted with mature trees.

The castle was built during the 19th century and underwent multiple renovations to maintain its original architecture. These efforts allowed the building to preserve historical details while incorporating modern amenities for continued use.

The castle operates today as a venue for weddings, family celebrations, and business events, reflecting how France repurposes historical buildings for contemporary use. Visitors can see how the rooms are arranged for different occasions and how the property serves the local community.

The estate lies near the former route nationale 518, now the RD 518, and is reached via the route de Rajat in Heyrieux. Three car parks with 150 spaces adjoin the grounds. The château is run as an event venue, so visits must be arranged beforehand.

The property unusually spans across two separate communes, an administrative quirk in the Rhône region. This geographic split sets it apart from typical estates and adds an intriguing layer to its location.
