The earliest known records of Dagsnäs estate date back to the 15th century, when it was owned by Gumsehuvud family. The current main building was built in 1772-1782 by Per Tham. The current appearance originates from the restoration made according the plan of Helgo Zettervall in 1874. Over the years several Viking age runestones from the region have been moved to the castle grounds.
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.
