Hohnstein Castle is located on a hard sandstone slab, 140 metres above the Polenz valley and is the major landmark of the small town. It was probably built around 1200 or earlier as a Bohemian border fortress for the Margravate of Meißen to defend it against Saxony. In 1353 the castle went into the possession of the Bohemian nobleman, Hynek Berka z Dubé, whose coat of arms with crossed oak branches decorates the entranceway to the second courtyard. In 1443 the Berkas of Dubá lost the estate through exchanges and purchase, only mentioned for the first time under their name, to the Electorate of Saxony under Frederick the Humble, although it remained a Bohemian fief until 1806. The Wettins used it as a base for hunting and for salmon spearing (Lachsstechen).
In the succeeding centuries the castle acted alternately as a seat of administration (electoral Amt), a court and a prison. The original wooden structures were gradually replaced during the 17th and 18th centuries by the present stone buildings and even successfully withstood a Swedish siege in 1639.
After the dissolution of the Amt in 1861 the castle served as a men's correctional institute (Männerkorrektionsanstalt) and from 1919 as a juvenile prison.
In 1925 the mighty castle became a youth hostel. In the years 1933/34 a concentration camp was established here for so-called protective custody prisoners (Schutzhäftlinge), in practice 5,600 political prisoners. During World War II a prisoner of war camp was housed in the castle and, after the war it was a refuge for displaced persons. From 1949 it was extended to become the largest youth hostel in the GDR. In 1953 the National Science Museum for Geology, Botany, Zoology and Ecology of the countryside was established here. In 1997 the castle was turned into a Friends of Nature house and youth guest house, to which the museum belongs today.
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.
