Located in the Germus mountains of south-eastern Anatolia, this property presents monumental round-oval and rectangular megalithic structures erected by hunter-gatherers in the Pre-Pottery Neolithic age between 9,600 and 8,200 BCE. These monuments were probably used in connection with rituals, most likely of a funerary nature. Distinctive T-shaped pillars are carved with images of wild animals, providing insight into the way of life and beliefs of people living in Upper Mesopotamia about 11,500 years ago.
