The City Walls are what makes Dubrovnik so recognizable all over the world.
They were built from the 13th to the 17th century for defense purposes. The City Walls are almost two kilometers long (1,940 meters) and 25 meters tall. The Walls are reinforced by towers facing the four cardinal directions. At the time the Walls were initially built, there were only 2,000 people living inside and the walls changed their shape as time passed. The Walls as we know them today were built in the 15th and the 16th century. The construction was carried out swiftly because Dubrovnik was constantly at risk of siege.
