The Sloupsky castle lies at the south border of Sloup over the valley of the Dobranovsky stream. The origin, history and the position of this castle is not exactly known till nowadays. The historians suppose it used to stand at the northeast root of the rock where it was protected by surrounding ponds and swamps. Some medieval buildings survived at the top. They probably served as a shelter during wars. The today’s precincts cut into the limestone rock are from 17th and from the beginning of 18th century when hermitage was founded there. Nowadays the 35metres high limestone formation is considered as the rock castle.
