Carcassonne and its citadel
Carcassonne, a medieval city unique in Europe
Carcassonne’s spectacular walled medieval citadel is protected by no less than 52 towers.
The town below has plenty of history too, founded in the 12th century. Here, see how the Canal du Midi progresses through the Aude Valley up to the Fresquel Aqueduct – this early 19th-century canal-bridge with its three arches has the advantage of allowing both the canal and a road to cross the Fresquel River side by side.
