Gobekli Tepe is a complex of monumental stone enclosures in southeastern Turkey, built around eleven thousand years ago by people who had not yet adopted farming. That combination, monumental architecture before agriculture, is why it matters and why what it means is argued about.

The site consists of circular and oval enclosures of massive T-shaped limestone pillars, the largest around five metres tall and weighing several tonnes, carved in relief with foxes, snakes, boars, cranes, scorpions, and abstract symbols. The pillars have arms and hands rendered on their sides, suggesting stylised human or more-than-human figures. Excavation began under Klaus Schmidt in 1995, and the site was inscribed as a UNESCO World Heritage Site in 2018. Only a fraction has been excavated.

The dating is secure and is the source of the site's significance: construction began in the tenth millennium BC, before pottery, before metal, and before domesticated plants and animals in the region.

Schmidt's interpretation, which made the site famous, was that it was a sanctuary rather than a settlement, built by mobile hunter-gatherers who gathered periodically, and that the labour of building and feeding the builders created pressure to secure a reliable food supply. On this reading religion drove agriculture rather than agriculture enabling religion, reversing the standard sequence.

That reading is now substantially disputed by later excavation at the site itself. Evidence of domestic occupation has been reported, including cisterns, grinding equipment in quantity, and traces of dwellings, which suggests a settled or semi-settled community rather than an empty ritual centre visited by pilgrims. Some researchers argue the temple-versus-village dichotomy is itself the error, and that in a society without our categories a building could be both.

Whether the builders were purely hunter-gatherers is also less clear than the popular account suggests. The plants they ate were wild, but wild cereals were being intensively gathered and processed in the region, which is the stage immediately preceding domestication rather than a world innocent of it.

A reconstruction of hunter-gatherer social life. Whether the builders were mobile foragers gathering periodically, or a more settled community, is the central open question about the site.

The site attracts an unusual volume of claims outside the archaeological literature, including proposals that it records a comet impact, encodes astronomical alignments, or evidences a lost civilisation. These are not the mainstream position and generally rest on selective use of the carvings, whose iconography is not deciphered and may not be a notation at all. The genuine debate is narrower and more interesting: not whether a lost civilisation built it, but whether monumental religion preceded farming, followed it, or grew alongside it.
