History

The Château de Mauvezin is located in the commune of Mauvezin in present-day France. The site’s origins trace back to prehistoric times, serving as a refuge for local communities about two thousand years ago. These early inhabitants used the natural defensibility of the site to shelter from attacks, marking the beginning of its long history as a fortified position.

During the 11th century, the Counts of Bigorre established the first stone castle on this strategic hilltop. This initial construction laid the foundation for the fortress that would evolve over the centuries. In the late 14th century, around 1380, Gaston III de Foix-Béarn, famously known as Gaston Fébus and a prominent military leader during the Hundred Years’ War, undertook significant rebuilding and enlargement of the castle. His work modernized the defenses and reflected the military needs of the era. The castle remained under the control of the Béarn-Foix family, who later acquired the title of Kings of Navarre. By the end of the 16th century, the castle came into the possession of Henry IV of France through succession.

After 1607, when the county of Bigorre was incorporated into the French kingdom, the Château de Mauvezin ceased to have military importance. The military garrison stationed there was removed, and the fortress gradually fell into neglect. Over time, local villagers took stone from the castle ruins for building materials. During this period of decay, the castle’s dilapidated state became entwined with local folklore, which spoke of witches’ gatherings and ghostly apparitions lingering within its walls.

The decline was halted in the 19th century when local authorities intervened to protect the site from further stone removal. Efforts to conserve the remains began, although restoration was delayed until the 20th century and interrupted by the two World Wars. In December 1941, the castle and its main tower, or donjon, were officially recognized as a French historic monument, securing their protection. Restoration proceeded through the 20th century, eventually preserving the structure as a heritage site.

Remains

The Château de Mauvezin presents a classic example of medieval military architecture seen in southern France. The overall layout is a nearly perfect square, with each side measuring approximately 35 meters. The stone walls reach heights between 15 and 18 meters and are strengthened by seven large buttresses that provide additional support. These curtain walls are crowned by a 2-meter-wide chemin de ronde, a defensive walkway along the top used historically by defenders to patrol and defend the fortress.

At the heart of the castle stands its donjon or main tower, originally built in the 11th century and serving as the cornerstone around which the rest of the fortress was developed. This tower rises to around 37 meters in height, with walls as thick as 3.5 meters at the base, tapering to 2 meters near the summit. The massive stone construction reflects its defensive purpose, designed to withstand sieges and attacks.

The castle walls incorporate building materials quarried from nearby Arros, primarily large stone blocks combined with occasional courses of brick. Lime mortar, holding the masonry together, was produced from local quarries northwest of the site. The defensive design includes machicolations—openings in the wall parapets that allowed defenders to drop or shoot projectiles onto attackers directly below—and square towers attached not only at the corners of the curtain walls but also at their midpoints, enhancing the fortress’s protective capabilities.

Above the main gate, stone heraldry marks the castle’s identity, engraved with the motto “J’ay belle dame” and bearing the coat of arms of the Foix-Béarn family, signifying the patrons responsible for its medieval expansions. Within the courtyard, one can find a medieval siege engine, a ballista, historically used for launching projectiles at besieging enemies. Inside the donjon, restorers have arranged six rooms to illustrate scenes of medieval daily life, bringing together archaeological findings and historical context.

Today, the castle has been fully restored and retains much of its original grandeur. The structure overlooks the Arròs valley, offering sweeping views of the Pyrenees to the south. Its thick stone walls, defensive towers, and preserved medieval features stand as a testament to its long history from prehistoric refuge to fortified medieval stronghold.
