Dubrovnik City walls
The city of Dubrovnik is completely surrounded with walls and forts, including the Old Port. The history of the fortifications goes back to the early Middle Ages. No doubt the earliest urban settlement upon the islet of Laus was protected with walls. The fact that the city was able to resist the Saracens who besieged the city for 15months in the 9th century means that it was fortified well. The city first spread towards the uninhabited eastern part of the islet. The eastern section was included within the defence walls in the 9th and 10th century. When the sea channel separating the city from mainland was filled with earth in 11th century, the city merged with the settlement on land and soon a single wall was built around the area of the present-day city core. The whole city was enclosed in the 13th century, except for the Dominican monastery, which came under their protection not before the 14th century. The average thickness of the wall was 1.5 meters, and it was built of stone and lime. To increase the strength of the walls and ensure better defence, 15 square forts were built in the 14th century.
UPDATE: Many emails have asked whether I have visited Croatia. During my really active traveling for work days I was banned from entering most countries behind the Iron Curtain. Now that the iron veil of communism has been lifted I plan to visit Croatia and other countries in the area. My wife's family is from just across the Adriatic in the Abruzzi region of Italy, so, I hope to see this beautiful area soon. Friends have said that the people are as amazing as the country.
