Building A was the first of the monumental buildings to be discovered at the site in an area that is now known as the Main Excavation Area or Southeast-Hollow. This building is not round-oval but has two straight parallel 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 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. Continued excavations in Building A would probably lead to the discovery of further pillars.
