In the eastern Arabian Peninsula, the Al-Ahsa Oasis is a serial property comprising gardens, canals, springs, wells and a drainage lake, as well as historical buildings, urban fabric and archaeological sites. They represent traces of continued human settlement in the Gulf region from the Neolithic to the present, as can be seen from remaining historic fortresses, mosques, wells, canals and other water management systems. With its 2.5 million date palms, it is the largest oasis in the world. Al-Ahsa is also a unique geocultural landscape and an exceptional example of human interaction with the environment.
