The castle in Bobolice was built by King Casimir III the Great in the middle of the 14th century, probably in place of an earlier wooden structure. The castle was a part of the defence system of royal strongholds protecting the western border of Poland on the side of Silesia. In 1370, immediately after becoming King of Poland, Louis I the Great granted the castle to Władysław Opolczyk, Duke of Opole, as a prize for his support of the king’s dynastic plans. Nine years later Opolczyk leased the castle to Andrzej Schoen, a Hungarian from Barbalas; the new owner manned it with Germans and Czechs, who robbed local inhabitants and conspired with the Teutonic Order. Dissatisfied with their behaviour, the Polish king Władysław Jagiełło invaded Bobolice in 1396 and took over the castle with adjacent estates. The castle is situated on a steep rocky hill (360 m above sea level). Up till now, only the upper part of the stronghold (the residential building with at least two storeys and remnants of the cylindrical wall tower) has survived. The castle was accessible through a drawbridge over the dry moat, and the entire construction was surrounded by walls with battlements, made of local white limestone. Currently reconstruction works are under way in order to restore the entrance gate and the circumferential wall around the castle grounds.
