In the 13th century, the Cathar Crusade of Pope Innocent III against heretics of Languedoc brought to submission many cities in the South of France. To his crusaders, the pope promised all the lands which they would free of Cathars. Of course, landlords of Languedoc didn’t like the idea of their properties being used as a prize. Together with the Cathars, they held the fort in their castles for 10, 20, and, in some cases, 50 years. Most of the castles were located on inaccessible rocks. Today, you will find just their remnants, but some of them have kept their greatness.
