Gripenberg Castle (Gripenbergs slott) is a wooden manor house. It is considered to be the biggest wooden castle in Sweden and one of the oldest that remain today as well.
The castle was built in 1663 as a huntig seat for the field marshal Carl Gustaf Wrangel. Its architect is unknown, but there is some reason to believe, that it might have been Nicodemus Tessin the Elder. It is assumed that the castle's name is derived from the name of Wrangel's mother Margareta Grip and that Wrangel might have chosen it to commemorate her. By the end of the 17th century the castle was bought by Samuel von Söderling and remained in the possession of his family until today.

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.
