Cité de Carcassonne

The Cité de Carcassonne (Occitan: Ciutat de Carcassona [siwˈtat de kaɾkaˈsunɔ]) is a medieval citadel located in the French city of Carcassonne, in the Aude department, Occitania region. It is situated on a hill on the right bank of the river Aude, in the south-eastern part of the city proper. The citadel was restored at the end of the 19th century by the theorist and architect Eugène Viollet-le-Duc. In 1997, it was added to the UNESCO list of World Heritage Sites because of its exceptional testimony to the architecture and planning of a medieval fortress town.
