Mirepoix Cathedral (Cathédrale Saint-Maurice de Mirepoix) foundation stone was laid by Jean de Lévis on the 6th May 1298. Construction continued, with interruptions, over the next six centuries. The cathedral was restored in 1858 and 1859. The cathedral has the second widest Gothic arch in Europe (after Girona in Catalonia, Spain).
Inside the cathedral vandalism and demolitions has destroyed many treasures but you can still admire a tabernacle, a Christ on the cross from the 14th century and seven paintings by Larivière-Vesontius.
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.
