Göbekli Tepe Megalithic Complex

Around 9600 BCE, hunter-gatherer societies in southeastern Anatolia constructed Göbekli Tepe, a monumental ritual complex featuring circular enclosures with massive T-shaped limestone pillars weighing up to 10 tons. Some pillars were carved with reliefs of wild animals, abstract symbols, and human-like features. The construction required sophisticated social organization among hunter-gatherers, challenging theories that agriculture preceded complex social structures. Evidence suggests that the need to build and maintain such ritual centers may have contributed to the development of agriculture in nearby areas. The site was deliberately backfilled around 8200 BCE, preserving its structures until rediscovery by modern archaeologists.
