Hochburg castle was founded probably by Dietrich von Hachberg in the 11th century - although the first written mention dates from 1127. Between 1553-1577 the fortifications were completely remodeled and seven bastions were added in the early 1600s. Hochburg was however destroyed by catholic forces in the Thirty Years' War in 1634-1636. The reconstruction and modernization took place in 1660-1678, but it was again destroyed by German volunteers in 1681 to prevent an attack by French forces. The final destruction occured in 1688 by troops of Louis XIV.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.
