In 1609, Zikmund von Tiefenbach acquired the castle by marriage. Rudolf von Tiefenbach, an older brother of Zikmund, was a Protestant at that time, yet he remained loyal to the Catholic Emperor (and later converted to Catholicism). On November 8, 1620, at the Battle of White Mountain, he and his regiment sided with the Imperial Army (i.e. against rebellious Bohemian Estates). As a reward for its loyalty to the Catholic emperors Tiefenbach family could keep the castle and adjacent manor even after the majority of Bohemian Protestant nobility was confiscated and expelled into exile.
