The Vörös torony (Red Tower), a 15C medieval keep, is the oldest part of this fortress. The castle was rebuilt in Renaissance style in the early 16C. The castle’s atmosphere is evident as soon as you enter the tower. The great hall or Nagy Palota, decorated with sculpted figures, and the fireplace room are magnificently preserved. In the corner tower, another room boasts a fine keystone with rose design, under which conspirators in the struggle for national independence met in secret.
