Located in France.
The Cité de Carcassonne is a medieval architectural ensemble that is located in the French city of Carcassonne in the department of Aude, region of Occitanie. It is located on the right bank of the Aude, southeast of the current city. This fortified medieval city, whose origins date back to the Gallo-Roman period, owes its fame to its double enclosure, reaching nearly 3 km in length and comprising fifty-two towers, which dramatically dominates the valley of Aude. The city also includes a castle (the Count’s castle) and a basilica (Saint Nazaire basilica).
Saved from the destruction by the action and tenacity of the archaeologist Jean-Pierre Cros-Mayrevieille, then restored in the nineteenth century in a sometimes controversial way under the direction of Viollet-le-Duc then Boeswillwald, the City of Carcassonne is, since 1997, listed as a UNESCO World Heritage Site. The Count’s Castle, the fortifications, and the towers belong to the State and are managed by the Center of National Monuments, while the Lices and the rest of the City are part of the municipal domain.
