The Cité de Carcassonne

History and visitor guide to Carcassonne — Europe's largest medieval walled city, restored in the 19th century and now a UNESCO World Heritage Site.

The Cité de Carcassonne

Decline and Restoration

The Treaty of the Pyrenees in 1659 moved the Franco-Spanish border south, making Carcassonne's strategic position irrelevant. The fortifications were abandoned, quarried for stone by locals, and the Cité decayed into a slum. By 1849, the government proposed demolishing the walls entirely.

The historian Jean-Pierre Cros-Mayrevieille and the writer Prosper Mérimée (then Inspector of Historic Monuments) campaigned to save Carcassonne, and in 1853, the architect Eugène Viollet-le-Duc was commissioned to restore it. Viollet-le-Duc's restoration was brilliant, controversial, and in places frankly inventive — he added the pointed slate witch-hat roofs on the towers, which are northern French rather than Languedocian in style (the originals were flat terracotta). Purists have debated his choices ever since, but the result is one of the most visually striking fortified sites in the world.

What to See

Château Comtal

The inner citadel, built by the Trencavel viscounts in the twelfth century and rebuilt by the Crown after 1226. The museum inside covers the history of the site, the Cathar period, and Viollet-le-Duc's restoration. The rampart walk from the château offers the best views of both wall circuits and the Aude valley below.

Basilique Saint-Nazaire

A Romanesque nave with Gothic transepts and choir, containing some of the finest stained glass in southern France — fourteenth-century windows depicting the life of Christ and the Tree of Jesse. The contrast between the austere Romanesque columns and the luminous Gothic glass is striking.

The Ramparts Walk

The full circuit of the between the two walls takes about 30 minutes and gives a visceral sense of the defensive engineering. In summer, the lower lices host jousting tournaments and medieval festival events.
