Göbekli Tepe is a Neolithic archaeological site in Upper Mesopotamia (al-Jazira) in modern-day Turkey. The settlement was inhabited from around 9500 BCE to at least 8000 BCE, during the Pre-Pottery Neolithic. It is known for its large circular structures that contain large stone pillars – among the world's oldest known megaliths. Many of these pillars are decorated with anthropomorphic details, clothing, and sculptural reliefs of wild animals, providing archaeologists insights into prehistoric religion and the iconography of the period. The 15 m (50 ft) high, 8 ha (20-acre) tell is covered with ancient domestic structures and other small buildings, quarries, and stone-cut cisterns from the Neolithic, as well as some traces of activity from later periods.
