A cliff castle that bears a curious resemblance to Peyrousse is Trosky, in Bohemia, but in this latter case the rocks are of basalt, and between the two towers the connecting rock forms a deep depression. In 1415, Johann von Herzmanmiestetz and Otto Berka of Trosk sacked the monastery of Opatowitz, butchered most of the monks, tortured the abbot so that he died a few days later, and carried off all the plunder they could collect. With the spoil Otto Berka built a castle on the two spires of rock, a tower on each, and connected them with a crescent wall, and a gallery of communication. The walls were six feet thick, and the foundations clamped to the rock with iron. He also contrived a tunnel, cut in the rock to the bottom, to enable himself and his men to ascend and descend. In 1424, however, Otto Berka was there no more. The castle was besieged by the terrible one-eyed Hussite commander, Ziska with the Flail, and he succeeded in capturing the lower tower after great loss of life, but entirely failed to take the upper donjon. After the departure of Ziska the castle was taken as a residence by Margaret, widow of Otto Berka, who secured the lower tower, and her granddaughter Barbara occupied the higher. These women hated each other as poison, and to personal hate was added religious rancour, for Barbara had embraced the party of the Utraquists. The theological quarrel was simply about the use of the chalice at communion. The Roman Church had withdrawn it from the people; the Utraquists asserted their right to it; and about this question the two parties fought and slaughtered each other, and burnt towns and castles. The tradition is that all day long, and part of the night, the two women screamed abuse at each other from their several towers, and desisted only for their meals, their devotions, and necessary sleep. Folk passing along the highway would halt and listen to the yelling and vituperation of the two shrews. Each had her own chapel at the foot of the cliffs, in which each ostentatiously followed the rite of which she approved; and to this day the chapels remain. According to the local story, the cries of the women were so strident and so continuous that all birds were scared away from Trosky. At length Margaret died, and Bertha had become so accustomed to scolding at the top of her voice, that she died soon after from dissatisfaction at having lost the object of her abuse. In 1468 Trosky was the property of William von Hasenburg, who sided with King Mathias against George Podjebrad. After the defeat of Mathias, Podjebrad captured Trosky, but as the owner came to terms, he was allowed to retain his castle. The towers are all that remain of the castle; the curtain wall has been broken down. The lower tower can be reached by a climber with a steady head, but not without risk of life. The higher tower is quite inaccessible. From the height a magnificent prospect is obtained, with Prague in the distance.
