It is made up of 13 structures of various sizes and different functions, distributed around four civic-ceremonial plazas. However, it should be noted that there were never more than six or seven of these constructions at the same time. All the buildings of the architectural complex have been explored and, most of them, have been fully restored.

Building D5-2: It is the one with the best construction quality. It has three autonomous rooms with vaulted ceilings and ornamentation on both sides of the central door. The architecture and decoration suggest another elite residence.

Building D5-5: To the north of Plaza A is located building D5-5, which corresponds to the Early Classic. It is actually a 10 m high substructure formed by a pyramidal base and topped by a temple, which is reached by a staircase with two landings on its south façade. The upper façade of the temple is a very old zoomorphic doorway, since it is possible to appreciate two oval and stucco-covered recesses that are interpreted as a pair of eyes. In the interior two tombs belonging to high rank personages were detected, which denotes the cult to the dead rulers.

Building D5-10: Building D5-10 is located on the eastern side of Plaza A. The main façade faces Plaza B, which it delimits to the south. It is the second most important building of the South Group. It was built and abandoned during the Early Classic. It has a single room that was once roofed with a vault, but still retains the main access in the center of the north façade, as well as a secondary access in the rear wall. The presence of a bench or bed inside the room suggests that it functioned as a residence for the local elite. At the front there are four masonry pillars that suggest a huano palm or grass roof.
