Dubrovnik, the historic Ragusa Republic
The strong circular Minčeta Tower, the 14th-century fortress located at the highest point of the old town and the walls at the northern part of Dubrovnik. The main wall on the land side is 4 to 6 metres thick, and, at certain locations, the walls reach up to 25 meters in height. In total, the walls are 1940 metres long with 6 fortresses.
