~ Walls of Ston ~ The longest stone wall in Europe
This Croatian sea town is located in Dubrovnik – Neretva Country, and its history dates back to the distant Middle Ages and early 14th century. Built on the model of Dubrovnik, Ston can boasts the longest stone wall in Europe, incredible 5.5 kilometers long. Also known as the City of salt, it used to have great value because of the white gold which he abounds and we can recall the period 14th and 15th century, when the exchange of kilo of salt per kilo of gold was commonly. Today he owns sections of the oldest active salt pant in the world, which still, from ancient times, produces salt in a traditional and natural way.
Ston city walls consist of the main wall and three forts (Veliki Kaštio, Koruna and Podzvizd), forty-one towers, seven bastions, (Sokolić, Arcimon in Ston, the three bastions of Veliki Kaštel, the Podzvizda bastion and the Arcimon in Mali Ston), four pre-walls (the eastern and south-western Ston pre-walls, the Mali Ston pre-wall and the Korun pre-wall), and a water-filled moat that stretches around the western, southern and eastern edges of Ston. The construction of these magnificent walls began in early 16th century.
The walls of Stone were a massive architecture and construction feat. Originally 7000-meters long (22 965 ft.), they consist of several parts; the Stone city walls, the Mali Ston city walls and the Big wall with its three forts. Its forts and towers are strengthened by 10 round and 31 square flanking towers and 6 semi-circular bastions.
