Montségur castle, the symbol of Cathar resistance rebuilt at the start of the 13th century, was once a refuge for Cathars hunted down by the Inquisition. The stronghold was besieged for 10 months before being taken by the royal army in March 1244, the month of the Prat dels Cremats ("field of the burned") tragedy when 225 Cathars who had refused to renounce their faith perished on a funeral pyre. A history and archaeology museum in the village of Montségur traces the history of the site and of Catharism through a rich collection of objects found during excavations at the castle.
Montségur fortress is perched on top of a rocky spur at an altitude of 1,207 metres and can be reached on foot in 30 minutes. In addition to its medieval remains, it offers visitors a magnificent panoramic view over the village below and the surrounding scenery.
