Okoř is a castle on a low rocky promontory in Okoř, north-west of Prague, about 15 kilometres from the city centre. In 1228 a stronghold was built in the small hamlet of Okoř. It was later modified into a Gothic castle, founded in 1359 by Frantisek Rokyčansky, a wealthy burgher of Prague's Old Town. It was later modified by comprehensive Late Gothic remodelling by the Lords of Donin. In 1518, during the reign of Bořitas of Martinice, the castle was turned into a residence in the Renaissance style.
During the Thirty Years' War the castle was heavily damaged and then restored in the Baroque style. It underwent further extension in the second half of the 15th century, and in the 17th century it was owned by Jesuits. Following their departure after the Jesuit order was discontinued in Bohemia, the Okoř castle became deserted in the late 18th century and slowly began to deteriorate.

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.
