For the whole time of its existence the castle was in the possession of the Berka family, who left it by the end of the 16th century. The cause of its destruction was the mine where millstone used to be exploited (in the 18th century). The fort is over 100 metres long but it was strongly affected by the mining activities. At present, the only preserved part is the wall with a gate. The nearby rock gate is not natural but man-made.
