How old are the Taş Tepeler sites?

The frame: PPNA and PPNB

Almost all dating in this region is expressed with two labels, so they are worth knowing.

PPNA — Pre-Pottery Neolithic A, roughly 9600–8800 BCE. The earlier phase. Round buildings, no farming, no pottery.

PPNB — Pre-Pottery Neolithic B, roughly 8800–7000 BCE, often split into early, middle and late. Rectangular buildings become common; domestication is under way by the later part.

A rough rule: PPNA is the monument horizon, PPNB is the village horizon. The great circular enclosures belong to the earlier end; partitioned houses to the later.

Site by site

Göbekli Tepe — the best-dated site by a wide margin, excavated since 1995 with an extensive radiocarbon programme. Monumental phase from around 9500 BCE (PPNA), with occupation continuing into the PPNB, and a commonly cited overall range of roughly 9600–8000 BCE.

Karahan Tepe — broadly contemporary with Göbekli Tepe, tenth into ninth millennium BCE. Excavation began only in 2019, so much of its public dating rests on comparison rather than a published radiocarbon sequence.

Sayburç — late PPNA into early PPNB, with figures in the region of 8650–8300 BCE discussed from the excavation. A short, essentially single-layer occupation.

Harbetsuvan Tepesi — early PPNB, so after Göbekli Tepe's earliest monumental phase.

Ayanlar Höyük — dated by Bahattin Çelik from surface material to between the early and middle PPNB. Excavation began only in September 2025, so this is survey-based and may be revised.

Sefertepe and Çakmaktepe — Pre-Pottery Neolithic, within the same broad horizon. Both are active excavations whose absolute chronologies are still being established; Çakmaktepe is discussed as early-horizon material.

Gürcütepe — the outlier at the young end. All four mounds are PPNB, with the easternmost later still in the PPNC. Later than Göbekli Tepe, not contemporary with it.

Why the precision varies so much

The gap between Göbekli Tepe and everything else is not a matter of importance. It is a matter of excavation years.

Göbekli Tepe has had three decades of work and a mature radiocarbon programme tied to defined stratigraphic contexts. Karahan Tepe has had since 2019. Ayanlar has had one season.

So when a site is described as 'the same age as Göbekli Tepe', that often means the material looks similar, which is a reasonable inference and not the same as a dated sequence. Both are legitimate; they carry different weight.

What complicates every one of these dates

Fill is not architecture. Several of these buildings were filled in. Material in the fill can be older or younger than the structure holding it, so a date from fill does not date the building.

Sites have phases. 'How old is Karahan Tepe' has at least four answers — first occupation, construction of the chamber, filling, abandonment.

Reuse and rebuilding. Göbekli Tepe's special buildings show multiple phases, with structures modified over long periods.

This is why careful sources give ranges rather than single years, and why a headline date should always prompt the question: dating what, exactly?

The honest summary

The Taş Tepeler sites span roughly 9600 BCE to 7000 BCE — around two and a half thousand years, which is longer than the gap between us and classical Athens.

Treating them as one moment flattens that. The people who raised Göbekli Tepe's enclosures and the people who lived in Gürcütepe's partitioned houses were separated by more time than separates us from the Roman Empire.

'Twelve thousand years old' is a serviceable headline for the oldest end of it. It is not a description of the group.
