The site encompasses the Amida Mound, known as İçkale (inner castle), the 5.8km-long city walls of Diyarbakir with their numerous towers, gates, buttresses, and 63 inscriptions from different periods, as well as Hevsel Gardens, a green link between the city and the Tigris which supplied the city with food and water.
