The Departmental Council of Aude has committed itself to Act II of the Cathar Country, its local development programme, based on the heritage of 20 sites in its territory: 2 cities (Carcassonne, Fanjeaux), 10 castles (Villerouge Terménès, Aguilar, Termes, Puilaurens, Quéribus, Peyrepertuse, Arques, Lastours, Saissac and Montségur in Ariège), 7 abbeys (Fontfroide, Saint Papoul, Caunes, Villelongue, Lagrasse, Alet Les Bains, Saint Hilaire) and 1 museum (Quercorb). The renewal of the Act II Cathar Country programme is reflected in a partnership work around 5 projects (architectural signature, cultural transmediation, promotion, road signs and professionalisation of actors). The project presented under the ERDF POI 2014-2020 concerns the works and services to be carried out for the two “architectural signature” and “cultural transfer” projects for 12 sites in the Pyrenees massif: 8 castles (Villerouge Terménès, Aguilar, Termes, Puilaurens, Quéribus, Peyrepertuse, Arques and Montségur in Ariège), 3 abbeys (Lagrasse, Alet Les Bains and Saint Hilaire) and the Quercorb Museum. The other 8 sites are supported by the ERDF under the Languedoc-Roussillon OP 2014-2020.
