Building A was the first of the monumental megalithic building to be discovered during archaeological excavations at the site. Remarkably, this building is not round-oval but has straight lateral walls with an ‘alcove’ at its northern end. As Building A has not been excavated in its entirety, it cannot be ruled out that older (round-oval) phases of the building still remain undiscovered.
The central T-shaped limestone monoliths in Building A are adorned with different images of wild animals in low relief, including a ‘net of snakes’ and an unidentified quadruped on the western pillar, and an aurochs, fox and crane of the eastern pillar.
So far, only four further pillars can be assigned to Building A. These are integrated in the surrounding walls. It is highly likely that a continuation of excavations in Building A would lead to the discovery of further monoliths.

It dates from the 10th-9th millenium BC.
