Dubrovnik City Walls

The impressive walls enclosing the ancient city of Dubrovnik were laid out in the 13th century and became an ongoing project for almost two hundred years. The fortified walls are up to 10 feet (3m) thick on the sea side and at least twice as thick on the land side, reaching up to 82 feet (25m) in height. Visitors access the walls via a steep stone stairway and once they reach the top they'll be rewarded with astonishing vistas. A walk around the old city from this fascinating vantage point is a must for visitors to Dubrovnik. The detached sentinel of Lovrijenac Fort to the west of the old city is also worth a visit.
