Catal Huyuk in Turkey was a large Neolithic town dating between 7000-5000 BCE that has provided insight into early urban living. It had no streets, with houses built adjacent to one another and accessed through openings below the roof. Trade, especially in obsidian, supported the town's wealth. Numerous shrines decorated with paintings, reliefs, and skulls have also been found intermingled with houses, suggesting the religious importance. Wall paintings depicted human figures and groups in a variety of poses, showing early advances in representational human art.
