The magnificent Eriksberg Castle was built by statesman Erik Karlsson Gyllenstierna and completed after his death (1657) by his wife Beata von Yxkull. The castle was designed by famous architect Nicodemus Tessin the Elder. After possession of Gyllenstierna Eriksberg was left to decay, until it was restored in the 1800s by Carl Carlsson Bonde. Eriksberg is still privately owned by Bonde family, but the large park is open to the public. There are several form types, like Baroque and Italian park.
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.
