[EX Q]: Passage: The castle was built in the 13th century by Přemysl Otakar II or his son Václav II to guard royal paths and local mines. The first known owner was Mikuláš Winkler, burgrave of Loket Castle, who sold Hauenštejn to the monastery in Doksany. The monastery exchanged it for another building with King John of Luxemburg. His son Charles IV enlarged the castle‘s domain. The castle frequently changed its keepers in the second half of the 14th century and the 15th century but it more or less remained royal property. The rich family of Šlik that started silver mining near Jáchymov won the castle in the 16th century. The Šliks rebuilt the castle in the Renaissance style after a fire in 1600. In 1663 the Šliks sold the castle to the Saxe-Lauenburg ducal family and it became part of the Ostrov domain. The castle was in the hands of the Baden family from 1689. When the last male member of the family died in 1771, the property of the Badens in Bohemia was inherited by the royal family of Maria Theresa. The Habsburgs sold it to the Buquoy family in 1837. Countess Gabrielle Buquoy started to rebuild the castle in a Romantic style. Ferdinand Buquoy continued the reconstruction under the influence of historism, taking its examples from England (Windsor, Arundel, Belvoir, Lancaster or Oxford) and Bavaria (Hohenswangau, Lahneck).
