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 de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
