Bierzgłowski Castle was one of the oldest stuctures built by Teutonic Knights. The Gothic style castle was built between 1270-1305 to the site of previous castle (from the 1260s), which was destroyed by Lithuanians in 1263. Bierzgłowski castle has been rebuilt several times between 15th and 19th centuries. The castle has an unique ceramic relief in a one of portals. It depicts a horseman and two knights and is one of the oldest known Prussian ceramic artefacts.

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.
