Bolczów Castle is located near Janowice Wielkie. Building of the castle is attributed to Clericus Bolcze (Clericus Bolz), a courtier of duke Bolko II in the year 1375. Captured by Hussites, it was destroyed by the punitive expedition of Wroclaw and Swidnica townsmen. Since the 16th century, the castle was owned by Justus Decjusz (Jobst Ludwig Dietz), a courtier of Sigismund I the Old. He reconstructed the ruined castle and developed copper mining in the surroundings. After Decjusz's death, the castle became property of the Schaffgotsch family. It was destroyed again during the Thirty Years' War, when Swedes were looking for its treasures. After this invasion, Bolczów Castle never regained its splendor, even though it was partly reconstructed in the 19th century.
