Located in Turkey, Çatalhöyük is considered by many to be the world's first city. By 6500 B.C. its population of 3,000 was even more impressive.

The city included hundreds of mud-brick homes stacked on two mounds. It was so dense that people walked on the roofs of houses rather than streets.

The city had a rich culture, evidenced by murals, figurines, and ceremonial burial sites. A painting on one wall has been called the world's oldest map and the world's oldest landscape painting.

Çatalhöyük was abandoned around 5700 B.C.
