Develop your castrum - a fortified village - to face off the attacks of your adversaries, the crusaders and offer a refuge to the pursued Cathars. With the help of your faithful friends, cross Cathar Country in search of items that you will be able to combine in your WORKSHOP to save the Occitan culture from destruction. Castrum offers you: - A HISTORY mode, playable anywhere at any time, during which you collect items to develop your castrum. - A MONUMENT mode, playable only during your visit to the monuments of Aude, which lets you play geotagged mini games.

The 20 monuments of Cathar country: 10 CASTLES Aguilar castle Arques castle Montségur castle Peyrepertuse castle Puilaurens castle Quéribus castle Saissac castle Termes castle Villerouge-Termenès castle Lastours castle 7 ABBEYS Alet-les-Bains abbey Caunes-Minervois abbey Fontfroide abbey Lagrasse abbey Saint-Hilaire abbey Saint-Papoul abbey Villelongue abbey 2 MEDIEVAL SITES Castles and ramparts of the city of Carcassonne Medieval city of Fanjeaux 1 MUSEUM Quercorb museum Who are the Cathars? Appearing around the year 1000, Catharism was a dissident Christian religion, originating from the East, particularly influential around Toulouse, Carcassonne, Béziers and Albi. The region therefore became a refuge for the Cathars when the Church pursued them during the Albigensian crusade, all the way to the heights of Montségur. It is this saga that the castles of Cathar country recount.
