This UNESCO World Heritage Site is made up of seven components: three archaeological sites (the archaeological cities of Uruk, Ur and Tell Eridu, which form part of the remains of the Sumerian settlements that developed in southern Mesopotamia between the 4th and the 3rd millennium BCE in the marshy delta of the Tigris and Euphrates rivers) and the Ahwar of Southern Iraq, also known as the Iraqi Marshlands, one of the world’s largest inland delta systems, in an extremely hot and arid environment.
