Duchy of Nysa
The town was plundered during the Thirty Years' War (1618–1648). After the First Silesian War and the 1742 Treaty of Breslau the Duchy of Nysa was partitioned and Głuchołazy became a Prussian bordertown, while the adjacent area around Zlaté Hory remained with Austrian Silesia. In 1834 the town suffered a fire, and in the following decades large parts of the medieval walls were demolished. In the 19th century it became a spa town.
