Château de Montreuil-Bonnin

Château de Montreuil-Bonnin is a medieval fortress in the Boivre Valley with five towers built into a rocky hill. The stronghold features thick stone walls and defensive structures arranged in a compact layout that once protected the surrounding territory.

This fortress was built in the 13th century and served as a royal mint under French kings who expanded their territory. The structure played an important role in regional administration and royal control during the medieval period.

The fortress reflects how medieval power was displayed through imposing walls and defensive structures that dominated the surrounding landscape. Its layout shows the practical separation between military functions and residential spaces typical of the period.

You should wear sturdy footwear because the approach involves climbing a sloped path up to the fortress entrance. It is best to visit during warmer months when the pathways are dry and easier to navigate.

The central keep was severely damaged for centuries before major restoration work revealed its original construction methods in recent years. This recovery showed how medieval builders reinforced stone structures against damage and decay.
