Structure AD · The Structures
Known to the excavators as Structure AD, this is the largest building yet uncovered at Karahan Tepe — a great hall about 23 metres across, ringed with tiered benches and standing pillars. It looks like the communal heart of the whole site.
Structure AD is the largest building yet found at Karahan Tepe — a great chamber roughly 23 metres across, partly cut into the living bedrock and ringed with tiered stone benches and upright pillars. If the Pillar Room next door is the site's most mysterious space, Structure AD is its communal heart: a hall built to bring a large group of people together.
It is also one of the largest structures known from the entire Pre-Pottery Neolithic — which is remarkable for a community that had not yet taken up farming.
Like the rest of Karahan Tepe's core, Structure AD was made by carving down into the bedrock rather than building up from the ground. The result is a wide, partly sunken hall. Running around its interior are two-step (tiered) benches — low stone seats cut in two levels — while pillars stand against the walls and a pair of larger central pillars anchor the middle of the space. In the floor are deep pits, and excavators have found broken objects deliberately placed within the building.
The tiered benches are the telling detail. Seats arranged around a central focus are, almost by definition, architecture for assembly — for a group to sit together and attend to something happening in the middle, where the paired central pillars stand. Some reporting suggests the benches could seat on the order of a couple of hundred people. We'd put it carefully: Structure AD was clearly built to hold a substantial community at once. Exactly what they gathered for — ceremony, feasting, decision-making, or all of these — is not something the evidence yet settles, and we won't pretend it does.
Structure AD does not stand alone. It is joined to the neighbouring Pillar Room (Structure AB) — the sunken chamber of eleven pillars and the carved head — as part of a single connected core. Reading the two together, you get a sense of a designed complex: a large communal hall beside a smaller, more intense, more hidden chamber. Movement between the two seems to have mattered.
Like other buildings at Karahan Tepe, Structure AD was not simply abandoned. At the end of its life it was deliberately filled in and closed, with broken objects placed inside as part of the process. Whether we read that as a respectful "retirement" of the building or as something more ritually charged, the intent is clear: the hall was purposefully brought to an end, not left to decay.
We follow the evidence and the excavators here, and we're careful with the label. Structure AD is best described as a large central communal building — the site's principal gathering space. It is tempting to call it a "theater," a "temple," or a "council house," but those words import functions we can't yet demonstrate. What we can say is well supported: it was big, it was built for people to come together, its pillars gave the space a charged focal point, and it was ceremonially closed. The rest is still being excavated.
It is the largest building yet found at the site — a roughly 23-metre central communal hall, partly cut into the bedrock, with tiered benches, wall and central pillars, and floor pits. It was deliberately filled in at the end of its use.
About 23 metres in internal diameter, making it one of the largest known Pre-Pottery Neolithic buildings.
Its tiered benches point to communal gathering — a place for many people to come together. The precise purpose (ceremony, feasting, assembly) is still debated, and we avoid over-claiming a single function.
It was deliberately closed at the end of its life, with broken objects placed inside — a purposeful "closing" of the building rather than simple abandonment. The exact meaning is still discussed.
Karahan Tepe Research & Archive · Last updated July 2026.
Structure details (dimensions, tiered benches, central pillars, floor pits, and the closing fill) follow Prof. Necmi Karul's 2021 excavation report and official Taş Tepeler project material; capacity figures reported in secondary coverage are noted as such. We use the excavator's designation "Structure AD" as the canonical name and avoid assigning a single settled function. This is a living archive summary, not an official academic publication.
