Göbekli Tepe

Göbekli Tepe (ɟœbecˈli teˈpe 'Potbelly Hill') is a very old archaeological site in Upper Mesopotamia (al-Jazira) in modern-day Turkey. It was lived in from around 9500 BCE to at least 8000 BCE, during the Pre-Pottery Neolithic period. What makes Göbekli Tepe special are its large circular buildings with big stone pillars—some of the oldest known megaliths in the world. Many of these pillars have carvings of animals and human-like shapes, which give archaeologists clues about prehistoric religion and art.

The site was first used at the very start of the Neolithic period, when people began to live in permanent settlements for the first time. This period is linked to the Neolithic Revolution, when humans started farming. But Göbekli Tepe is interesting because it was built on a mountain with little sign of farming, making scientists wonder if people settled down because of farming or the other way around.

Recent discoveries show that Göbekli Tepe may have been a home to people, not just a place for ceremonies as once thought. Researchers found evidence of everyday life, like tools and ways to process grains. The big stone buildings might have been roofs over open spaces that fell down and were rebuilt many times. The style of building and carvings at Göbekli Tepe is similar to other nearby places from the same time, like Karahan Tepe.

Göbekli Tepe was first found during an archaeological survey in 1963. A German archaeologist named Klaus Schmidt realized its importance in 1994 and started digging there the next year. After he died in 2014, other scientists continued the work. In 2018, Göbekli Tepe became a UNESCO World Heritage Site, recognized as one of the earliest examples of huge buildings made by humans. So far, only about 10% of the site has been dug up, and more is being learned each year.

Geography and environment

Göbekli Tepe is near the village of Örencik in Şanliurfa Province in the Taş Tepeler, in the foothills of the Taurus Mountains. It overlooks the Harran plain and the headwaters of the Balikh River, a tributary of the Euphrates. The site sits on a flat limestone plateau, connected to the mountains by a narrow ridge and dropping steeply on other sides.

When people lived there, the area had more rain and was covered in open steppe grassland with lots of wild grains like einkorn, wheat, and barley. Herds of animals such as wild sheep, wild goat, gazelle, and equids lived nearby. The builders chose this spot because it gave them a good view of the plain and easy access to materials like soft limestone and flint for tools. They collected rainwater through carved channels leading to cisterns that could store a lot of water.

Dawn of village life

Göbekli Tepe was built and used during the earliest part of the Southwest Asian Neolithic, called the Pre-Pottery Neolithic (PPN), around 9600 to 7000 BCE. This time period marks the start of village life and the first permanent human settlements in the world. One early site is Körtik Tepe, dated to between 10,700 and 9,250 BC, which may have been a forerunner to the PPN culture.

Archaeologists study how people changed from hunting and gathering to farming during this time. The people of Göbekli Tepe were hunter-gatherers who also ate early farmed cereals. They lived in villages at least some of the year. PPN villages often had stone or mud brick houses, along with large buildings used for community activities. Göbekli Tepe is famous for its big circular buildings with tall stone pillars.

Chronology

Radiocarbon dating shows that the earliest structures at Göbekli Tepe were built between 9500 and 9000 BCE, during the Pre-Pottery Neolithic A period. The site was used until around 8000 BCE.

The site went through several building phases over more than 1,500 years. In the earliest phase, people built large circular enclosures and small round houses. Later, they added new walls and tall stone pillars. Over time, more rectangular houses were built, and the site was changed to deal with landslides. Eventually, the big enclosures were abandoned, and smaller buildings were put up among the old ruins.

Architecture

The first circular buildings at Göbekli Tepe appeared around the latter half of the 10th millennium BCE. These structures ranged from 10 to 30 meters in diameter and featured T-shaped limestone pillars set within thick walls of unworked stone. Four such circular buildings have been uncovered, and surveys suggest there may be 16 more, with nearly 200 pillars in total. The pillars are the oldest known megaliths in the world.

Many pillars are decorated with abstract symbols and carvings of animals such as lions, bulls, and birds. Some pillars even have human arms carved on them, possibly representing stylized human figures. Later buildings were rectangular and often had polished lime floors. These structures continued to serve important cultural functions for the people of the time.

Construction

Göbekli Tepe sits on a plateau shaped by erosion and old stone quarrying. There are channels on the southern part of the plateau that might be from an ancient quarry. Most of the structures seem to come from Neolithic quarrying, where big stone blocks were cut from the rock and moved to build the site.

Scientists have different ideas about how many people were needed to build Göbekli Tepe. Some think it needed hundreds of people to move the heavy stones, while others believe just a few people could have done it with ropes and water. Experiments show that small groups could have built the structures in a few months.

Tools

Göbekli Tepe has many flint tools found from the top of the ridge to the slopes. In 1963, more than 3,000 tools were found, mostly made of excellent quality flint with a few made of obsidian. Common tools included cores, blades, flakes, scrapers, burins, and projectile points.

Excavations in one small building found almost 700 tools, mostly retouched pieces, along with scrapers and tools with a special shine called gloss. Researchers also found over 7,000 grinding stones, which may have been used to process plants, though it is not clear if these plants were wild or grown by people.

Iconography

The stone pillars at Göbekli Tepe are shaped like a T and many are carved with pictures. Most of the carvings show animals such as snakes, foxes, boars, gazelle, wild sheep, onagers, ducks, and vultures. The animals are often shown in strong, active poses.

Besides animals, the pillars sometimes show abstract shapes like H-shaped symbols, crescents, and disks. Human figures are rare, but when they appear, they are often shown without heads or in simple forms. Some scholars believe the animals may have been carved to protect the people or to represent important symbols.

Interpretation

Klaus Schmidt believed that Göbekli Tepe served as a ritual center where small nomadic groups would gather for building projects and large feasts before moving on. Evidence from animal bones suggests these events happened when food was most plentiful.

Schmidt also thought the people there may have practiced shamanic traditions. He believed the T-shaped stone pillars might represent human forms, possibly ancestors, rather than gods, which he thought came later. Some think the site could have been more than just a place for rituals, perhaps also used as a community space. The idea that it was an ancient observatory has not been supported by the researchers working there.

Research history

Before archaeologists studied it, the hill where Göbekli Tepe stands was thought to be a sacred place by local people.

The site was first noticed in 1963 during a survey led by Halet Çambel and Robert John Braidwood. In 1994, German archaeologist Klaus Schmidt revisited the site and began excavations. He discovered huge stone pillars and recognized them as ancient megaliths, not grave markers as previously thought. Schmidt led the excavations until his death in 2014. Today, research at Göbekli Tepe continues under the direction of Necmi Karul, focusing on preserving and documenting the site.

Conservation

Göbekli Tepe was named a UNESCO World Heritage Site in 2018 because it is one of the earliest examples of large buildings made by people. As of 2021, only about 10% of the site had been dug up and studied by scientists.

There was some discussion in 2018 about how the site was being cared for. One scientist thought that building a new path to the site might have hurt it, but the Ministry of Culture and Tourism said they did not use harmful materials and that the site was safe.
