The Vieux-château de l'île d'Yeu ("Old castle of the Isle of Yeu") is a fortification on the island of île d'Yeu. Olivier IV de Clisson, a great builder of castles, undertook the work with the aim of protecting the islanders in the event of foreign invasion. The longest of these had been led by the famous English pirate, Robert Knolles, who managed to seize the castle in 1355 and occupied the island for 37 years. In 1381, the île d'Yeu was retaken during the reconquest of Poitou by Olivier V de Clisson.
During the Renaissance, Jean V de Rieux, master of the isle, erected towered walls around the castle. This type of construction was carried out by Italian engineers brought back from the Italian Wars by King Francis I. Later, Vauban perfected this style of military architecture for his famous forts. This protection proved effective in 1550 when several thousand Spanish soldiers attacked from the north. Held in check under the walls by the local garrison, they were forced to retreat by sea to the Iberian peninsula.
The Vieux-château, made obsolete by the construction between (1654 and 1660) of small coastal forts following Vauban's technique, was demolished at the end of the 17th century, along with several other ancient castles on the French coast, by order of Louis XIV, worried that they could be taken by an enemy and used as strong points.
Hergé was inspired by the Vieux-château in the design of the Adventures of Tintin comic book The Black Island.
References:The Pilgrimage Church of Wies (Wieskirche) is an oval rococo church, designed in the late 1740s by Dominikus Zimmermann. It is located in the foothills of the Alps in the municipality of Steingaden.
The sanctuary of Wies is a pilgrimage church extraordinarily well-preserved in the beautiful setting of an Alpine valley, and is a perfect masterpiece of Rococo art and creative genius, as well as an exceptional testimony to a civilization that has disappeared.
The hamlet of Wies, in 1738, is said to have been the setting of a miracle in which tears were seen on a simple wooden figure of Christ mounted on a column that was no longer venerated by the Premonstratensian monks of the Abbey. A wooden chapel constructed in the fields housed the miraculous statue for some time. However, pilgrims from Germany, Austria, Bohemia, and even Italy became so numerous that the Abbot of the Premonstratensians of Steingaden decided to construct a splendid sanctuary.
