Le Château de Ranrouët

Herbignac, France

---

Le Château de Ranrouët in Herbignac, France, is a medieval fortress and noble residence that began construction in the 13th century and was continually modified until the 17th century.

It uniquely stands in the marshlands near the Guérande peninsula, using natural barriers for defense. Over the centuries, its owners adapted it to evolving military needs, including artillery defenses in the 14th century and Renaissance-style residential additions in the 16th century. The castle was slighted by royal order in 1618 and later abandoned, before being set on fire during the French Revolution.

Today, ruins remain, revealing the castle’s historical significance as a military stronghold and noble home. It is recognized as a historic monument and offers visitors insight into the evolution of military architecture and the history of Brittany.
