Brahehus Castle was built by Per Brahe between 1637 and 1650s. Soon after Per Brahe died in 1680 Brahehus was abandoned and moved as a Crown property in the Great Reduction under Charles XI of Sweden. In 1708 the castle was destroyed by fire and not rebuilt anymore. From the ruins you have a fantastic view of lakes Vättern and Visingsö.
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.
