It is located to the southeast of the main plaza; it has several structures in process of intervention.

Structure VI: Its main access stairway is located in the central part of the building; there are other smaller stairways on the east side. In the central façade there are cascades of masks in profile and vestiges of a zoomorphic mask in its superior part, besides remains of crestería crowning its highest part. In the east and west ends it is possible to appreciate two annexes added later, formed by series of rooms that once had vault, but that still conserve the passacordeles to the sides of the openings.

Structure VII: It is directly linked to the construction phases of VI until both were integrated into a single platform, although at first they were built independently. In fact, building VII, with a view to the east, has three originally vaulted rooms, without any communication between them but with well elaborated benches. In front of these rooms there is a large area or rest located on the platform.
