Vieux-château de l'Île d'Yeu

Vieux-château de l'Île-d'Yeu is a medieval stone fortress perched on a rocky headland surrounded by the Atlantic Ocean, featuring four round towers and a central courtyard. The structure reveals distinct architectural phases spanning from the 14th to the 17th centuries.

The fortress was built in the 14th century during the Hundred Years' War and fell under English occupation from 1355 to 1392. It returned to French control after this period of foreign rule ended.

The castle reveals remnants of medieval daily life through its bakery, blacksmith, and kitchen spaces that visitors can still see today. Walking through these rooms gives a sense of how people actually lived and worked within these stone walls.

The fortress is accessible via walking paths and offers ocean views from its towers. Visitors should wear sturdy footwear since access involves uneven rocky terrain in places.

The castle inspired Belgian illustrator Hergé when he created scenes for the Tintin comic series. Its dramatic island setting and distinctive silhouette appear in several adventures of the famous fictional reporter.
