The Royal Castle in Chęciny was erected on a limestone hill (367 m. a.s.l.), because it was supposed to be an impregnable fortress. It stretches on the ridge of a rocky hill, which is perfectly visible from afar, and from the castle and its towers, visitors can admire the views of the area, see the Świętokrzyskie Mountains and even the Tatra Mountains. The castle was built at the turn of the thirteenth and fourteenth centuries, on the initiative of Wenceslaus II, king of Bohemia and Polish. The fortress played an important role as a place of concentration of Polish troops in preparations for the war with the Teutonic Order. The castle also served as a residence for Polish rulers and their families. The building is one of the first defensive brick structures in Lesser Poland.
