The Kysak Castle was also called Drienov, from the name of the knight Peter Drienov from the mighty family of Aba, who at the end of the 13th century was in possession of the surrounding lands. In 1283, he divided the property between his five sons, the oldest of whom, George, received the village of Kysak. He fought in the 80s of the thirteenth century against Cumans and Tatars and perhaps because of the desire to protect the lands from the invaders, he raised the castle Kysak. Already in the first half of the fifteenth century, the branch of the descendants of George’s family died away, and the property was taken over by the neighbors from Žehna. Kysak was on the border of their estate, so they did not look after it, and eventually at the beginning of the 16th century the castle was abandoned.
The castle had a very elongated, up to 62 meters long, shape, adapted to the ridge of the hill on which it was erected. The width of the castle only ranged between 9 and 12.5 meters. On the western edge a cylindrical tower (bergfried) with a diameter of 7.5 meters was erected, more or less in the central part a small building with a basement and another building and four-sided tower in the eastern part of the castle. Tower flanked the nearby gate, to which a timber bridge was led, over the ditch.
The castle was protected by two transverse ditches, of which the larger, north-eastern had a width of 18 meters and a rocky bottom at a depth of 10 meters from the edge of the castle hill. A second ditch with an earth rampart surrounded the western part of the castle. In addition, the western part of the castle was surrounded by a defensive wall, running along the entrance road, which surrounded the stronghold under the control of the cylindrical tower from the south to the northeast, where there had to be an entrance to the outer ward. It had a shape similar to a triangle, was protected by a ditch and separated from the castle core by the aforementioned transverse ditch, over which a wooden bridge was placed. The defensive walls of the outer ward were connected to the fortifications of the upper castle and, at the same time closed access to the ditch protecting it from both sides.
The castle has not survived to modern times. Traces of it are limited to the relics of the wall of a residential building and the hollow where the cylindrical tower was. You can reach the top of the hill with an unmarked, forest road from the village in about 30-40 minutes.
