Vieux-château de l'Île d'Yeu
The Vieux-château de l'Île d'Yeu is a medieval coastal fortification on Île d'Yeu off the Vendée coast of France, constructed and modified from the 14th century and reinforced during the Renaissance. Built of rough local stone and sited directly on a jagged granite promontory, it guarded the island approaches and is today a protected historic monument preserved as a partial ruin.

What Vieux-château de l'Île d'Yeu looked like in its prime.
Massive grey rough-hewn stone curtain walls and two prominent cylindrical round towers sit directly on a jagged granite promontory, their bases merging with the rock. The taller eastern tower shows corbelled machicolations and small rectangular gun‑loops; a lower round tower anchors the seaward flank. Low crenellated parapets and a battered wall profile run between the towers. A timber access bridge leads to the entrance over a narrow rocky inlet; the sea and tidal pools lap the rock below.
Its story
The story of Vieux-château de l'Île d'Yeu.
Olivier IV de Clisson, a great builder of castles, undertook the Vieux-Château to protect the islanders of Yeu in the event of foreign invasion. It did not always hold: the English pirate Robert Knolles seized the castle in 1355 and occupied the island for 37 years, before Olivier's son, Olivier V de Clisson, retook the Île d'Yeu during the reconquest of Poitou.
During the Renaissance Jean V de Rieux, master of the isle, ringed the castle with towered walls of the kind built by the Italian engineers King Francis I had brought back from the Italian Wars. The protection proved effective in 1550, when several thousand Spanish soldiers attacked from the north, were held in check under the walls by the local garrison, and were forced to retreat by sea to the Iberian peninsula.
The small coastal forts built to Vauban's technique between 1654 and 1660 made the old castle obsolete, and at the end of the seventeenth century Louis XIV — worried that an enemy might seize the old coastal castles as strong points — had it demolished. Classified a monument historique since 1900, the ruin had one more afterlife: Hergé drew on the Vieux-Château for The Black Island in The Adventures of Tintin.
