Вацлав I
Leśna Castle, erected on the border with the Polish Duchy of Silesia about southeast of the town, was first mentioned in a 1247 deed. King Wenceslaus I of Bohemia, then ruler of the Upper Lusatian lands, ceded it to the Meissen bishop Conrad I of Wallhausen. The fortress probably lost its strategic importance with the construction of Czocha Castle further east in the early 14th century.
