The first mention of the castle of the duke bishop of Dorpat dates from 1322, when it was destroyed by the army of the grand duke of Lithuania Gediminas. At that time it was a roadside watchtower guarding the southern trade route from Dorpat to Ruthenia and the eastern border of the Dorpat bishopric. Because of its frontier location, the castle was repeatedly besieged and demolished, both by Lithuanian and Ruthenian armies. Like the entire bishopric of Dorpat, Kirrumpah was destroyed in 1558 by the army of Ivan the Terrible, but the castle itself was saved from the final demolition by the local population, thanks to which it took part in the struggle in 1656 and 1701. At the latest from the beginning of the 18th century it was in ruin, its remains unfortunately served as a source of building material, with the expansion of the modern city of Võru.
The castle in its original form consisted of a mighty tower and a courtyard south-east of it, surrounded by a wall. Even then, the chapel had to function in the castle. In the second half of the fifteenth century, the rebuilding was made. The western fortifications and the cannon tower, located in the south-west corner of the main castle, were added to the existing fortifications. It was probably at that time that the main castle courtyard was partially built up.
At present, only the very modest stone relics on the hill resemble the existence of the castle. Entrance to the castle area is free.
