Göbekli Tepe is an ancient archaeological site located in southeastern Turkey, near the city of Şanlıurfa. The site is believed to date back to the Pre-Pottery Neolithic period, between 9,000 and 10,000 BCE, making it one of the oldest known human-made structures in the world.
Göbekli Tepe consists of several circular and rectangular structures made of large stone pillars, some of which are decorated with intricate carvings and reliefs of animals and humans. The site is believed to have been a ceremonial center where ancient people gathered to perform rituals and ceremonies, and some experts have suggested that it may have been one of the world's first temples.
The discovery of Göbekli Tepe has challenged traditional beliefs about the development of human civilization, as it suggests that the construction of monumental architecture and the development of organized religion may have preceded the development of agriculture and settled communities. The site is recognized as a UNESCO World Heritage Site and continues to be the subject of ongoing archaeological research and excavation.
