Wik Castle is one of the best preserved medieval castles in Sweden. The first owner was Israel And in the end of 13th century. The current magnificent castle with seven floors was built in the late 15th century. The massive walls and moats made the stronghold impregnable. During the Middle Ages, the castle was one of the sturdiest strongholds in the Mälaren Valley, and Gustav Wasa once besieged Wik Castle for over a year without ever managing to get inside the walls. It was modified to the present French-style appearance in the 17th century.
Wik Castle has been owned by several noble families like Sparre, Bielke, Horn von Liewe, de Geer and von Essen. Today it is owned by the county council of Uppsala and used primarily for the council's own conference activities. It is at present closed to the public.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.
