Château de Clisson

Château de Clisson is a castle ruin positioned on a rocky hilltop above the Sèvre Nantaise river, featuring round towers and defensive walls. The structure spreads across the elevated terrain with multiple sections of fortifications that show different periods of construction.

The fortress was built in the 13th century by Guillaume de Clisson as a strategic defense point along Brittany's borders. Over subsequent centuries, it was expanded and modified to meet changing military needs and threats.

The ruins attract those interested in medieval military design and the fortress's role protecting Brittany's borders. Artists and sketchers frequently visit to capture the dramatic stone forms and layers of history visible in the walls.

The site sits on a hillside with steep pathways, so proper footwear is important and not all areas are easily reached. The elevated location offers good views of the ruins, and visitors should allow time to explore the different sections at a comfortable pace.

The fortress displays uncommon defensive features like arrow slits and cannon openings that show how medieval warfare evolved. These details are less obvious than the outer walls but reveal the engineering innovations that made this fortification effective.
