Origin and history

La Garnache Castle, located in the Vendée department, is one of the oldest in the region. Its history begins in the 10th century with the construction of a castral mound, followed in 1045 by the construction of a wooden fortress, then in stone in the 13th century. This castle, composed of six round towers and a square tower connected by courtines, dominated a fortified town whose ramparts still remained in the seventeenth century. Its strategic position at the border of Brittany, Poitou and the Kingdom of France, as well as the proximity of the salt marshes, made it a major military and economic issue.

The destruction of the castle was ordered by Louis XIII in 1631, on the advice of Richelieu, to suppress local Protestant resistance. Some historians, such as Charles Mourain de Soudeval, specify that the decision to shave the building would have been taken in 1622, after the Battle of the Island of Re. The towers, the only remaining remains, were classified as historical monuments in 1925. In 2017, an attempt to acquire the site publicly by the municipality failed, despite the commitment of a local heritage association.

Under the castle, a network of undergrounds attests to its defensive role. One of them, starting from the East Tower, crosses the moth and leads to the Seudre stream, while another, independent, leads to a circular chamber. These developments illustrate medieval fortification techniques, designed to resist seats and facilitate escapes.

The remains of the castle, now privately owned, recall its historic importance in an area marked by conflicts between local and central authorities. Although partially destroyed, the site retains remarkable architectural elements, which are evidence of its strategic past between the Middle Ages and the modern era.
