Libštejn castle is located above the Berounka south of Liblín in the Rokycany district. The castle was built by the royal construction manager Ulrich Tista von Liebstein as a private residence and was first mentioned in writing in 1361. At the end of the 14th century the castle came into the possession of the lords of Kolowrat. In the Hussite Wars belonged Libštejn Bedřich von Kolowrat, who, together with his brother Hanuš, was an important opponent of the Hussites.
In 1425 the castle was besieged by the Hussites and shot at from the surrounding hills. After seven weeks of siege, the two brothers signed an agreement with the Hussites and switched to their side. In 1590 the castle was mentioned as desolate. The main building of the castle were two adjoining palas buildings, which formed a small elongated courtyard in the middle. On the short sides, the courtyard was accessed by a square residential tower. The hilltop castle was built between three other higher peaks. This militarily unfavorable choice of location is due to the calm and stable times of Charles IV.
