Short answer
Göbekli Tepe was recorded but dismissed in a 1960s survey, then recognised by Klaus Schmidt in 1994, who excavated it from 1995 — and in 2021 the Turkish-led Taş Tepeler programme turned it from a lone wonder into the coordinated study of a dozen related sites.
Work continues under the German Archaeological Institute (directed by Lee Clare) with Istanbul University and the Turkish authorities. Only a fraction of Göbekli Tepe has been dug — geophysical survey shows many more enclosures still underground.
Overlooked, then recognised
Göbekli Tepe was not unknown. A survey by Istanbul University and the University of Chicago recorded the mound in the 1960s, but its scatter of limestone was mistaken for a medieval cemetery and dismissed. The hill kept its secret for another thirty years.
In 1994 the German archaeologist Klaus Schmidt re-examined the site and understood at once what the flint and limestone meant. Excavations began in 1995, run by the German Archaeological Institute (DAI) with the Şanlıurfa Museum. What emerged rewrote the story of the Neolithic.
After Schmidt
Klaus Schmidt led the work until his sudden death in 2014. The project continued under the DAI — today directed by Lee Clare — in partnership with Istanbul University and the Turkish authorities, with a strong shift toward conservation, dating, and careful publication of the vast material Schmidt uncovered. Göbekli Tepe was inscribed as a UNESCO World Heritage Site in 2018.
Crucially, only a fraction of the site has been excavated — geophysical survey shows many more enclosures still underground. Göbekli Tepe is not a finished story.
The story keeps being revised
A working excavation changes its own mind, and Göbekli Tepe is a good example. Schmidt's influential idea that the enclosures were deliberately backfilled is now qualified by the current team, who attribute much of the fill to slope collapse and displaced midden. Evidence for domestic activity on the mound — long thought absent — has grown. And Gürcütepe, once assumed to be the village of Göbekli's builders, turned out to be later.
None of this is failure; it is how careful archaeology works. It is also why anything written about these sites should be read with an eye to when it was written.
The precedent that was almost lost: Nevalı Çori
Göbekli Tepe's T-pillars did not arrive without warning — there had been a rehearsal, and it was nearly drowned. In the early 1980s Harald Hauptmann excavated Nevalı Çori, a Pre-Pottery Neolithic settlement in the Euphrates valley with a 'cult building' containing T-shaped pillars and remarkable sculpture (Hauptmann 1993). It was the first clear sight of the tradition Göbekli Tepe would later reveal at scale.
Then the rising waters of the Atatürk Dam flooded Nevalı Çori in 1992. Klaus Schmidt had worked there, and it was partly that experience that let him grasp, two years later, what the limestone at Göbekli Tepe really meant. The recognition of Göbekli Tepe was built on a site that no longer exists.
The surveyors who mapped the network
The famous excavations rest on decades of quieter survey work. Much of what we know about the smaller T-pillar sites — Taşlı Tepe, Hamzan Tepe, Kurt Tepesi, Harbetsuvan, Sefer Tepe — comes from the field surveys of Bahattin Çelik, who published site after site through the 2000s and 2010s (for example Taşlı Tepe in 2011). It is largely that survey record that turned Göbekli Tepe from an isolated marvel into one node in a dense regional pattern.
That is the shift the current program formalises. Karahan Tepe, recorded in a 1997 survey, became the focus of major excavation from 2019 under Necmi Karul of Istanbul University; its rock-cut rooms and sculptures made the case for a whole connected landscape impossible to ignore.
The Taş Tepeler program, and its scale
In 2021 the Turkish Ministry of Culture and Tourism launched the Taş Tepeler research program, coordinating excavations across a cluster of Pre-Pottery Neolithic sites in the Şanlıurfa region — Göbekli, Karahan, Sayburç, Sefertepe, Çakmaktepe, Ayanlar Höyük and more. That shift, from single site to connected world, is the frame this whole site is built around.
By its fifth anniversary in 2025 the project reported 219 researchers from 36 institutions — Turkish and international — working across twelve active excavations at once. Göbekli Tepe itself, a UNESCO World Heritage Site since 2018, remains barely touched: geophysical survey shows many more enclosures still underground. This is not a finished story being written up; it is an open excavation whose picture is still changing season by season — which is exactly why anything written about these sites should be read with an eye to when it was written.
Common questions
Who discovered Göbekli Tepe?
It was recorded but dismissed in a 1960s survey; Klaus Schmidt recognised its significance in 1994 and began excavations in 1995 with the German Archaeological Institute and the Şanlıurfa Museum.
Who excavates Göbekli Tepe now?
The German Archaeological Institute (DAI), directed by Lee Clare, with Istanbul University and the Turkish authorities, following Klaus Schmidt's death in 2014.
What is the Taş Tepeler program?
A research initiative launched by Türkiye's Ministry of Culture and Tourism in 2021, coordinating excavations across ~a dozen related Pre-Pottery Neolithic sites in the Şanlıurfa region.
