Located in the north-central portion of the site, it was a space dedicated to civic-religious activities. It is made up of 14 buildings that delimit a rectangular plaza open on the south side.

Building 1: It is a pyramidal base of 10 meters high composed of six staggered bodies and a stairway with alfardas on the south façade. Most of the sculptural monuments found are associated with this building. In front of it a monolithic altar of circular form is conserved that rests on three supports elaborated in limestone rock. On the west side of it is attached a low platform partially explored, which is known as Building 14 and perhaps corresponds to an early construction stage.

Building 2: Following a north-south axis, in the center of the plaza is Building 2, a small quadrangular foundation (it is 1.35 m high) composed of two stepped bodies. The first has a slightly sloping wall, topped with a perimeter cornice. The second is a vertical wall only preserved in its lower part. It has staircases attached to the facades, limited by narrow alfardas.
