The Château de Courson was built in 1676. Originally the home of the Lamoignon family, the château has been in the same family since the 18th century. Its historic park was laid out in formal style by a pupil of André Le Nôtre in the 18th century. During the 19th century the gardens were twice remodelled, first around 1820 for the Duc de Padoue by the landscaper Berthault, then again around 1860 by the Bülhers, who laid out many French parks and gardens.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.
