Two hills form the 37&nbsp,ha site on the Southern Anatolian Plateau. The taller eastern mound contains eighteen levels of Neolithic occupation between 7400&nbspbc and 6200&nbspbc, including wall paintings, reliefs, sculptures and other symbolic and artistic features. Together they testify to the evolution of social organization and cultural practices as humans adapted to a sedentary life. The western mound shows the evolution of cultural practices in the Chalcolithic period, from 6200&nbspbc to 5200&nbspbc. &Ccedilatalh&oumly&uumlk provides important evidence of the transition from settled villages to urban agglomeration, which was maintained in the same location for over 2,000 years. It features a unique streetless settlement of houses clustered back to back with roof access into the buildings.
