The walls which enclose the town were built in the 10th century to face the Hungarian invasions. The castle sits near the main road and is still in fairly good condition. Rectangular in shape (60◊80), there is only one entrance at the center of the eastern wall, where signs of an old drawbridge can still be seen. The crenelated city walls have four small round lookout towers on each corner. Three more towers are situated at the center of the north, south and west walls. The square keep is now a bell tower.
