Located in modern-day Turkey, Göbekli Tepe is one of the world’s oldest known temples. This site features massive carved stones and complex architectural structures that predate Stonehenge by some 6,000 years. The sophistication and scale of Göbekli Tepe suggest that the community was able to coordinate large-scale projects, indicating a high level of social organization and spiritual or communal life. Without evidence of permanent residential structures from this site, these people were more likely hunter-gatherers that stuck to the area, and not farmers.
