Château de Ranrouët

Château de Ranrouët is a castle ruin in Brittany whose remains span several centuries of construction and later partial reconstruction. The site contains stone walls, multiple defensive towers, and residential structures that reflect different periods of medieval building techniques.

The fortress was founded in the 13th century to control access to the Guérande peninsula and underwent modifications until the 17th century. During the French Revolution, the structure was dismantled but has since been partially restored.

The site takes its name from the Ranrouët family, a local noble lineage that controlled the territory for centuries. Visitors can observe traces of this aristocratic presence in the remaining residential quarters and fortified structures.

The ruins are open to visitors who can walk through freely, with guided tours providing additional context about the structures. The site is best visited during warmer months when the grounds are fully accessible and visibility across the surrounding landscape is clear.

The castle displays a rare blend of military fortress and noble residence in its original layout, illustrating its dual purpose as both a control point and home. This interplay between defensive installations and living spaces allows visitors to grasp how medieval fortifications evolved into residential seats.
