Cathar castles: why their possible inclusion on UNESCO's World Heritage List is so divisive

The seven medieval fortresses of Aude and Ariège, known for decades as the "Cathar castles," could be inscribed on UNESCO's World Heritage List during the World Heritage Committee session held from July 19 to 29 in Busan, South Korea. The nomination dossier, submitted by the Mission Patrimoine Mondial association, now presents them under the name "Royal Fortresses of Languedoc," within a group called "System of Fortresses of the Seneschal's Court of Carcassonne (13th-14th centuries)."

This name change has sparked a heated controversy in the region. A petition against the new name has already gathered nearly 8,500 signatures, and a demonstration is planned for July 18 at Quéribus Castle. Opponents argue that the term "Cathar castles" is part of the area's historical and touristic identity and fear that the role of Catharism will be gradually erased from collective memory.

A name deemed more faithful to history

Proponents of the project point out, however, that the fortresses visible today were built after the Albigensian Crusade, during the reign of Louis IX, to protect the French border from Aragon and to control the territories newly annexed to the crown. While Cathar communities did indeed find refuge on several of these sites, the current buildings are royal fortifications erected after their demise. The proposal also includes the city and ramparts of Carcassonne, considered the center of this defensive system.

Beyond the historical debate, the stakes are also economic. In several rural communities, elected officials hope that the UNESCO designation will boost tourism and fund the upkeep of monuments weakened by time and weather. In Quéribus, visitor numbers have fallen from approximately 92,000 in 1995 to nearly 50,000 today. World Heritage status would offer international visibility, potentially revitalizing the local economy and strengthening the preservation of these iconic sites in southern France.
