Duchy of Jawor
The castle of Chojnik was originally raised by the order of Duke Bolko I the Strict in 1292 at the site of a former hunting lodge built by his father Bolesław II the Bald. The fortress was meant to protect the borders of Bolko's Duchy of Jawor against the menacing Wenceslaus II of Bohemia. Bolko's grandson Bolko II the Small, the last independent Piast duke, had the castle reconstructed starting from 1355.
