The walls were 1.90 meters thick and 6.60 meters high. Entrance to the town was through northern, southern and eastern gates.
In the 16th century, the medieval town walls were replaced with new, longer, and stronger walls.
The new walls enclosed the area of the present town centre and comprised corner towers, a fortress and several small towers on the inner side.
The walls were 1.90-meter-thick and 6.60 meters high. Entrance to the town was possible through northern, southern and eastern gates. Individual parts of the tower and walls are still partly preserved and visible. The photos show the remains of the town walls under today's post office, while a ground plan of the tower and walls is shown on the road pavement.
