The Carmelite Church is Gothic and was built in the 14th century. It has a wealth of treasures, including gravestones and the choir stalls (15th century). That the Carmelite monks honoured Our Lady can be seen in the many illustrations of Mary e.g. the Grape Madonna (outside the church), the Madonna in the Rosary and the Pieta. The former Carmelite monastery is now the Town Hall.References:
The Château Comtal (Count’s Castle) is a medieval castle within the Cité of Carcassonne, the largest city in Europe with its city walls still intact. The Château Comtal has a strong claim to be called a 'Cathar Castle'. When the Catholic Crusader army arrived in 1209 they first attacked Raymond-Roger Trencavel's castrum at Bèziers and then moved on to his main stronghold at Carcassonne.
The castle with rectangular shape is separated from the city by a deep ditch and defended by two barbicans. There are six towers curtain walls.
The castle was restored in 1853 by the architect Eugène Viollet-le-Duc. It was added to the UNESCO list of World Heritage Sites in 1997.
