Göbekli Tepe, Turkish for "Potbelly Hill", is an archaeological site in the Southeastern Anatolia Region of Turkey, approximately 12 km (7 mi) northeast of the city of Şanlıurfa. The tell has a height of 15 m (49 ft) and is about 300 m (980 ft) in diameter. It is approximately 760 m (2,490 ft) above sea level.

The tell includes two phases of use believed to be of a social or ritual nature dating back to the 10th–8th millennium BCE. During the first phase, belonging to the Pre-Pottery Neolithic A (PPNA), circles of massive T-shaped stone pillars were erected – the world's oldest known megaliths. More than 200 pillars in about 20 circles are currently known through geophysical surveys. Each pillar has a height of up to 6 m (20 ft) and weighs up to 20 tons. They are fitted into sockets that were hewn out of the bedrock. In the second phase, belonging to the Pre-Pottery Neolithic B (PPNB), the erected pillars are smaller and stood in rectangular rooms with floors of polished lime. The site was abandoned after the PPNB. Younger structures date to classical times.

The details of the structure's function remain a mystery. It was excavated by a German archaeological team under the direction of Klaus Schmidt from 1996 until his death in 2014. Schmidt believed that the site was a sanctuary where people from a wide region periodically congregated, not a settlement.


The site was first noted in a survey conducted by Istanbul University and the University of Chicago in 1963. American archaeologist Peter Benedict identified lithics collected from the surface of the site as belonging to the Aceramic Neolithic, but mistook the stone slabs (the upper parts of the T-shaped pillars) for grave markers, postulating that the prehistoric phase was overlain by a Byzantine cemetery. The hill had long been under agricultural cultivation, and generations of local inhabitants had frequently moved rocks and placed them in clearance piles, which may have disturbed the upper layers of the site. At some point attempts had been made to break up some of the pillars, presumably by farmers who mistook them for ordinary large rocks.

In 1994, Klaus Schmidt of the German Archaeological Institute, who had previously been working at Nevalı Çori, was looking for another site to excavate. He reviewed the archaeological literature on the surrounding area, found the 1963 Chicago researchers’ brief description of Göbekli Tepe, and decided to reexamine the site. Having found similar structures at Nevalı Çori, he recognized the possibility that the rocks and slabs were prehistoric. The following year, he began excavating there in collaboration with the Şanlıurfa Museum, and soon unearthed the first of the huge T-shaped pillars.


Gobekli Tepe TurkeyThe imposing stratigraphy of Göbekli Tepe attests to many centuries of activity, beginning at least as early as the Epipaleolithic period. Structures identified with the succeeding period, Pre-Pottery Neolithic A (PPNA), have been dated to the 10th millennium BCE. Remains of smaller buildings identified as Pre-Pottery Neolithic B (PPNB) and dating from the 9th millennium BCE have also been unearthed.

A number of radiocarbon dates have been published. The Hd samples are from charcoal in the fill of the lowest levels of the site and would date the end of the active phase of occupation of Level III - the actual structures will be older. The Ua samples come from pedogenic carbonate coatings on pillars and only indicate the time after the site was abandoned—the terminus ante quem.


Göbekli Tepe is on a flat and barren plateau, with buildings fanning in all directions. In the north, the plateau is connected to a neighboring mountain range by a narrow promontory. In all other directions, the ridge descends steeply into slopes and steep cliffs. On top of the ridge there is considerable evidence of human impact, in addition to the actual tell. Excavations have taken place at the southern slope of the tell, south and west of a mulberry that marks an Islamic pilgrimage, but archaeological finds come from the entire plateau. The team has also found many remains of tools.


The plateau has been transformed by erosion and by quarrying, which took place not only in the Neolithic, but also in classical times. There are four 10-metre-long (33 ft) and 20-centimetre-wide (7.9 in) channels on the southern part of the plateau, interpreted as the remains of an ancient quarry from which rectangular blocks were taken. These are possibly related to a square building in the neighbourhood, of which only the foundation is preserved. Presumably, this is the remains of a Roman watchtower which belonged to the Limes Arabicus. However, this is not known with certainty.

Gobekli TepeMost structures on the plateau seem to be the result of Neolithic quarrying, with the quarries being used as sources for the huge, monolithic architectural elements. Their profiles were pecked into the rock, with the detached blocks then levered out of the rock bank. Several quarries where round workpieces had been produced were identified. Their status as quarries was confirmed by the find of a 3-by-3-metre piece at the southeastern slope of the plateau. Unequivocally Neolithic are three T-shaped pillars that have not been levered out of the bedrock. The biggest of them lies on the northern plateau. It has a length of 7 m (23 ft) and its head has a width of 3 m (10 ft). Its weight may be around 50 tons. The two other unfinished pillars lie on the southern Plateau.

At the western edge of the hill, a lion-like figure was found. In this area, flint and limestone fragments occur more frequently. It was therefore suggested that this could have been some kind of sculpture workshop. It is unclear, on the other hand, how to classify three phallic depictions from the surface of the southern plateau. They are near the quarries from classical times, making their dating difficult.

Apart from the tell, there is an incised platform with two sockets that could have held pillars, and a surrounding flat bench. This platform corresponds to the complexes from Layer III at the actual tell. Continuing the naming pattern, it is called "complex E." Owing to its similarity to the cult-buildings at Nevalı Çori it has also been called "Temple of the Rock." Its floor has been carefully hewn out of the bedrock and smoothed, reminiscent of the terrazzo floors of the younger complexes at Göbekli Tepe. Immediately northwest of this area are two cistern-like pits, believed to be part of complex E. One of these pits has a table-high pin as well as a staircase with five steps.

At the western escarpment, a small cave has been discovered in which a small relief depicting a bovine was found. It is the only relief found in this cave.

Layer III

At this early stage of the site's history, circular compounds or temene first appear. They range from 10 to 30 metres in diameter. Their most notable feature is the presence of T-shaped limestone pillars evenly set within thick interior walls composed of unworked stone. Four such circular structures have been unearthed so far. Geophysical surveys indicate that there are 16 more, enclosing up to eight pillars each, amounting to nearly 200 pillars in all. The slabs were transported from bedrock pits located approximately 100 metres (330 ft) from the hilltop, with workers using flint points to cut through the limestone bedrock.

Two taller pillars stand facing one another at the centre of each circle. Whether the circles were provided with a roof is uncertain. Stone benches designed for sitting are found in the interior. Many of the pillars are decorated with abstract, enigmatic pictograms and carved animal reliefs. The pictograms may represent commonly understood sacred symbols, as known from Neolithic cave paintings elsewhere. The reliefs depict mammals such as lions, bulls, boars, foxes, gazelles and donkeys; snakes and other reptiles, arthropods such as insects and arachnids; and birds, particularly vultures. At the time the edifice was constructed, the surrounding country was likely to have been forested and capable of sustaining this variety of wildlife, before millennia of settlement and cultivation led to the near–Dust Bowl conditions prevalent today. Vultures also feature prominently in the iconography of Çatalhöyük and Jericho. Professor of Archaeology Steven Mithen suggests that in the early Neolithic culture of Anatolia and the Near East, the deceased were deliberately exposed in order to be excarnated by vultures and other carrion birds. (The head of the deceased was sometimes removed and preserved — possibly a sign of ancestor worship.) This, then, would represent an early form of sky burial, as still practiced by Tibetan Buddhists and by Zoroastrians in Iran and India.

Few humanoid figures have appeared in the art at Göbekli Tepe. However, some of the T-shaped pillars have human arms carved on their lower half, suggesting that they are intended to represent the bodies of stylized humans (or perhaps gods). Loincloths also appear on the lower half of a few pillars. The horizontal stone member on top is thought to symbolize a human head. The pillars as a whole therefore have an anthropomorphic identity. Whether they were intended to serve as surrogate worshippers, symbolize venerated ancestors, or represent supernatural, anthropomorphic beings is not known.

Some of the floors in this, the oldest, layer are made of terrazzo (burnt lime), others are bedrock from which pedestals to hold the large pair of central pillars were carved in high relief. Radiocarbon dating places the construction of these early circles in the range of 9600 to 8800 BCE. Carbon dating suggests that (for reasons unknown) the enclosures were backfilled during the Stone Age.

Layer II

Creation of the circular enclosures in layer III later gave way to the construction of small rectangular rooms in layer II. Rectangular buildings make a more efficient use of space compared with circular structures. They are often associated with the emergence of the Neolithic. But the T-shaped pillars, the main feature of the older enclosures, are also present here, indicating that the buildings of Layer II continued to serve as sanctuaries. Layer II is assigned to Pre-Pottery Neolithic B (PPNB). The several adjoining rectangular, doorless and windowless rooms have floors of polished lime reminiscent of Roman terrazzo floors. Carbon dating has yielded dates between 8800 and 8000 BCE. Several T-pillars up to 1.5 meters tall occupy the center of the rooms. A pair decorated with fierce-looking lions is responsible for the name "lion pillar building" by which their enclosure is known.

Layer I

Layer I is the uppermost part of the hill. It is the shallowest, but accounts for the longest stretch of time. It consists of loose sediments caused by erosion and the virtually uninterrupted use of the hill for agricultural purposes since it ceased to operate as a cult center.

The site was deliberately backfilled sometime after 8000 BCE: the buildings were buried under debris, mostly flint gravel, stone tools, and animal bones that must have been imported from elsewhere. In addition to Byblos points (weapon heads, i.e. arrowheads etc.) and numerous Nemrik points, Helwan-points and Aswad-points dominate the backfill's lithic inventory.

Chronological context

All statements about the site must be considered preliminary, as less than 5% of the site has been excavated, and Schmidt planned to leave much of it untouched to be explored by future generations (when archaeological techniques will presumably have improved). While the site formally belongs to the earliest Neolithic (PPNA), up to now no traces of domesticated plants or animals have been found. The inhabitants are assumed to have been hunters and gatherers who nevertheless lived in villages for at least part of the year. So far, very little evidence for residential use has been found. Through the radiocarbon method, the end of Layer III can be fixed at about 9000 BCE (see above) but it is believed that the elevated location may have functioned as a spiritual center by 11,000 BCE or even earlier, essentially at the very end of the Pleistocene.

The surviving structures, then, not only predate pottery, metallurgy, and the invention of writing or the wheel, but were built before the so-called Neolithic Revolution, i.e., the beginning of agriculture and animal husbandry around 9000 BCE. But the construction of Göbekli Tepe implies organization of an advanced order not hitherto associated with Paleolithic, PPNA, or PPNB societies. Archaeologists estimate that up to 500 persons were required to extract the heavy pillars from local quarries and move them 100–500 meters (330–1,640 ft) to the site. The pillars weigh 10–20 metric tons (10–20 long tons; 11–22 short tons), with one still in the quarry weighing 50 tons. It has been suggested that an elite class of religious leaders supervised the work and later controlled whatever ceremonies took place. If so, this would be the oldest known evidence for a priestly caste—much earlier than such social distinctions developed elsewhere in the Near East.

Around the beginning of the 8th millennium BCE Göbekli Tepe ("Potbelly Hill") lost its importance. The advent of agriculture and animal husbandry brought new realities to human life in the area, and the "Stone-age zoo" (Schmidt's phrase applied particularly to Layer III, Enclosure D) apparently lost whatever significance it had had for the region's older, foraging communities. But the complex was not simply abandoned and forgotten to be gradually destroyed by the elements. Instead, each enclosure was deliberately buried under as much as 300 to 500 cubic meters (390 to 650 cu yd) of refuse consisting mainly of small limestone fragments, stone vessels, and stone tools. Many animal, even human, bones have also been identified in the fill. Why the enclosures were buried is unknown, but it preserved them for posterity.


Gobekli Tepe Anatolia TurkeySchmidt's view was that Göbekli Tepe is a stone-age mountain sanctuary. Radiocarbon dating as well as comparative, stylistical analysis indicate that it is the oldest religious site yet discovered anywhere. Schmidt believed that what he called this "cathedral on a hill" was a pilgrimage destination attracting worshippers up to 150 km (90 mi) distant. Butchered bones found in large numbers from local game such as deer, gazelle, pigs, and geese have been identified as refuse from food hunted and cooked or otherwise prepared for the congregants.

Schmidt considered Göbekli Tepe a central location for a cult of the dead and that the carved animals are there to protect the dead. Though no tombs or graves have been found so far, Schmidt believed that they remain to be discovered in niches located behind the sacred circles' walls.

In 2017, discovery of human crania with incisions were reported, interpreted as providing evidence for a new form of Neolithic skull cult.

Schmidt also interpreted it in connection with the initial stages of the Neolithic. It is one of several sites in the vicinity of Karaca Dağ, an area which geneticists suspect may have been the original source of at least some of our cultivated grains (see Einkorn). Recent DNA analysis of modern domesticated wheat compared with wild wheat has shown that its DNA is closest in sequence to wild wheat found on Karaca Dağ 30 km (20 mi) away from the site, suggesting that this is where modern wheat was first domesticated. Such scholars suggest that the Neolithic revolution, in particular the beginnings of grain cultivation (i.e. not animal husbandry) took place here. Schmidt believed, as others do, that mobile groups in the area were compelled to cooperate with each other to protect early concentrations of wild cereals from wild animals (herds of gazelles and wild donkeys). Wild cereals may have been used for sustenance more intensively than before and were perhaps deliberately cultivated. This would have led to early social organization of various groups in the area of Göbekli Tepe. Thus, according to Schmidt, the Neolithic did not begin on a small scale in the form of individual instances of garden cultivation, but developed rapidly in the form of "a large-scale social organization".

With its mountains catching the rain and a calcareous, porous bedrock creating lots of springs, creeks and rivers the upper reaches of the Euphrates and Tigris was a refuge during the dry and cold Younger Dryas climatic event (10,800 – 9,500 BCE), and crowded conditions could have led these people to develop common rituals and gathering places to reduce tensions and conflicts over resources, and probably to mark territorial claims.

Schmidt engaged in some speculation regarding the belief systems of the groups that created Göbekli Tepe, based on comparisons with other shrines and settlements. He assumed shamanic practices and suggested that the T-shaped pillars represent human forms, perhaps ancestors, whereas he saw a fully articulated belief in gods only developing later in Mesopotamia, associated with extensive temples and palaces. This corresponds well with an ancient Sumerian belief that agriculture, animal husbandry, and weaving were brought to mankind from the sacred mountain Ekur, which was inhabited by Annuna deities, very ancient gods without individual names. Schmidt identified this story as a primeval oriental myth that preserves a partial memory of the emerging Neolithic. It is also apparent that the animal and other images give no indication of organized violence, i.e. there are no depictions of hunting raids or wounded animals, and the pillar carvings generally ignore game on which the society depended, such as deer, in favor of formidable creatures such as lions, snakes, spiders, and scorpions. Expanding on Schmidt's interpretation that round enclosures could represent sanctuaries, Gheorghiu's semiotic interpretation reads Göbekli Tepe's iconography as a cosmogonic map which would have related the local community to the surrounding landscape and the cosmos.


Göbekli Tepe is regarded by some as an archaeological discovery of the greatest importance since it could profoundly change the understanding of a crucial stage in the development of human society. Ian Hodder of Stanford University said, "Göbekli Tepe changes everything". If indeed the site was built by hunter-gatherers as some researchers believe then it would mean that the ability to erect monumental complexes was within the capacities of these sorts of groups which would overturn previous assumptions. Some researchers believe that the construction of Göbekli Tepe may have contributed to the later development of urban civilization. As excavator Klaus Schmidt put it: "First came the temple, then the city."

Not only its large dimensions, but the side-by-side existence of multiple pillar shrines makes the location unique. There are no comparable monumental complexes from its time. However surface surveys have shown several hills in the greater area to also have T-shaped stone pillars (e.g. Hamzan Tepe, Karahan Tepe, Sefer Tepe, Taslı Tepe), but there has so far not been much excavation done. These constructions seems to be smaller than Göbekli Tepe, and their placement evenly between contemporary settlements indicate that they were local social/ritual gathering places, with Göbekli Tepe maybe as a regional centre. So far none of the smaller sites are as old as the lowest Level III of Göbekli Tepe, but contemporary with its younger Level II (mostly rectangular rooms instead of circular). This could indicate that this type of architecture and associated activities originated at Göbekli Tepe and then spread to other sites.

A 500 years younger site is Nevalı Çori, a Neolithic settlement also excavated by the German Archaeological Institute and submerged by the Atatürk Dam since 1992. Its T-shaped pillars are considerably smaller, and its shrine was located inside a village. The roughly contemporary architecture at Jericho is devoid of artistic merit or large-scale sculpture, and Çatalhöyük, perhaps the most famous Anatolian Neolithic village, is 2,000 years later.

At present Göbekli Tepe raises more questions for archaeology and prehistory than it answers. It remains unknown how a force large enough to construct, augment, and maintain such a substantial complex was mobilized and compensated or fed in the conditions of pre-sedentary society. Scholars cannot interpret the pictograms, and do not know for certain what meaning the animal reliefs had for visitors to the site; the variety of fauna depicted, from lions and boars to birds and insects, makes any single explanation problematic. As there is little or no evidence of habitation, and the animals pictured are mainly predators, the stones may have been intended to stave off evils through some form of magic representation. Alternatively, they could have served as totems. The assumption that the site was strictly cultic in purpose and not inhabited has also been challenged by the suggestion that the structures served as large communal houses, "similar in some ways to the large plank houses of the Northwest Coast of North America with their impressive house posts and totem poles." It is not known why every few decades the existing pillars were buried to be replaced by new stones as part of a smaller, concentric ring inside the older one. Human burial may or may not have occurred at the site. The reason the complex was carefully backfilled remains unexplained. Until more evidence is gathered, it is difficult to deduce anything certain about the originating culture or the site's significance.


Future plans include construction of a museum and converting the environs into an archaeological park in the hope that this will help preserve the site in the state in which it was discovered.

In 2010, Global Heritage Fund (GHF) announced it will undertake a multi-year conservation program to preserve Göbekli Tepe. Partners include the German Archaeological Institute, German Research Foundation, Şanlıurfa Municipal Government, the Turkish Ministry of Tourism and Culture and, formerly, Klaus Schmidt.

The stated goals of the GHF Göbekli Tepe project are to support the preparation of a site management and conservation plan, construction of a shelter over the exposed archaeological features, training community members in guiding and conservation, and helping Turkish authorities secure UNESCO World Heritage Site designation for GT.
