Subsequently, the early Neolithic period has seen the emergence of substantial built environments in the form of villages and beyond.

Both the planning and the execution of the plan with accuracy were made possible by conceptualizing basic geometric ideas and methods such as circle, centre and compass arm.

In the archaeological record, architectural planning that includes specifications of architectural spatial forms prior to construction becomes archaeologically visible with the appearance of stone-built shelters in the late Epipaleolithic period (Natufian sites) in the Levant (Haklay & Gopher Reference Haklay and Gopher2015). Indeed, the results of the analysis brought to light an underlying geometric pattern which offers a new understanding of the assemblage of architectural remains indicating that three of the stone-built large enclosures were planned and initially built as a single project. This is done under the premise that such investigation would shed light on the chaîne opératoire of the enclosures' construction and their history, thus enabling a fresh look as well as an evaluation of past suggestions regarding these structures and the people who built them. The study presented here is an attempt to contribute in this direction by applying a preliminary architectural formal analysis in order to reconstruct aspects of the architectural design processes involved in the construction of the monumental enclosures. The building history and the chronological relations between the different structures (enclosures), however, remain in many ways a challenge and open to further analysis.

The excavation since 1995 has been accompanied by a lively discussion about the meaning and implications of its remarkable early Neolithic megalithic architecture, unprecedented in its monumentality, complexity and symbolic content. The site of Göbekli Tepe in southeastern Turkey keeps fascinating archaeologists as it is being exposed.
