The old city of Diyarbakr, located in southeast Turkey, is surrounded by an amazing system of fortifications known as the Diyarbakr City Walls. The walls were originally constructed during the Roman era, but other powers such as the Byzantines, the Abbasids, the Seljuks, and the Ottomans strengthened and expanded them.

With 82 towers, four main gates, and a length of more than 5 kilometers, the walls are constructed of black basalt stone. They have been designated as a UNESCO World Heritage Site because they are among the best-preserved examples of medieval military construction in existence.

 

The city walls were essential in defending Diyarbakr during numerous wars and sieges and in keeping the city safe from attackers. The city's historic and cultural legacy are represented by the walls, which are now a popular tourist destination.
