St. Jacob's church was built in the 11th and 12th centuries outside the fortifications around Cathedral Hill, and was used by numerous Jacob pilgrims on their way to Santiago de Compostela. Initially, the church was modelled around Heinrich's cathedral and was constructed as a column basilica. In 1771 the baroque facade was added, behind which numerous components from the romanesque period can still be discovered. Inside it is impossible to overlook the many romanesque elements.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.
