Although there is no precise data on the time of origin of the castle can be found in the castle inscriptions from 1233. A 25 -foot-tall tower is the tallest building in the castle. The castle has never served as a manor, but to safely store the income of farmers and to drive to trade. Also, the main road to the surrounding villages was so backed up.
