I am becoming aware that though Göbeklitepe is (so far) the greatest find, there are very many spots of similar antiquity in the region.
One is/was the Nevali Çori settlement that was submerged under rising waters in 1992 because of the Atatürk Dam. It lived through Roman, First Bronze Age and Chalcolithic periods, but its importance stems from finds from the Pre-Pottery Neolithic Period, dating back to 8000-8500 BC. 29 Structures were excavated, a type of house characterized by thick, multi-layered foundations made of large angular cobbles and boulders, the gaps filled with smaller stones so as to provide a relatively even surface to support the superstructure. These foundations are interrupted every 1-1.5m by underfloor channels, at right angles to the main axis of the houses, which were covered in stone slabs but open to the sides. They may have served the drainage, aeration or the cooling of the houses. An area in the northwest part of the village appears to be of special importance. Here, a cult complex had been cut into the hillside. It had three subsequent architectural phases, the most recent belonging to Stratum III, the middle one to Stratum II and the oldest to Stratum I. The two more recent phases also possessed a terrazzo-style lime cement floor (constructed of burnt lime and clay, colored red with ochre and polished), which did not survive from the oldest phase. Parallels are known from Cayönü and Göbekli Tepe. Monolithic pillars similar to those at Göbekli Tepe were built into its dry stone walls, its interior contained two free-standing pillars of 3 m height. The excavator assumes light flat roofs. Similar structures are only known from Göbekli Tepe so far. (Texts from museum mixed with Wikipedia information).
As the settlement has been submerged, the temple has been reconstructed in the museum. From the Pre-Pottery Neolithic B period such structures were built apart from the residential area. They had more details and more consideration was invested in building them. Unlike the other 28 structures it was square, at 14 x 14 metres. It went through a second building phase, in which materials from the earliest phase were re-used. Seating platforms surround the inner space. Across that platform 12 pillars were erected. In its centre there were two pillars of 2,35 metres. On their sides, human arms can be seen, ending in hands. They are interpreted as representing highly stylized human sculptures.
This is the reconstructed temple.
Another text explained: New lifeways which emerged in the Pre-Pottery Neolithic A period, which featured the cultivation of wild cereals, an increase in sedentary settlements, and the emergence of incipient hierarchical systems continued to develop in the subsequent Pre-Pottery Neolithic B period: settlements grew larger and crops and animals (sheep, goat, pig and finally cattle) were gradually domesticated. As for building, circular structures gave way to rectangular buildings in the PPNB. Load-bearing walls, corner joints, foundations and adobe bricks appeared, which would shape future architectural styles. By the end of PPNB two-storied, flat-roofed structures began to appear. Settlement were also characterized by a more planned appearance, featuring ceremonial squares, houses and activity areas.
PPNB ritual buildings also adhere to the characteristic rectangular ground plan of this period. Although smaller than their circular PPNA predecessors, these structures still feature many of the same elements, including the internal benches, terrazzo floors, and T-shaped pillars.
