This group of 15 buildings is on a natural elevation more than 60 m above river level, between the North Group and the West Platform of the Great Plaza. It is currently reached through a sidewalk that starts next to buildings 80, 31 and 32.

Building 42: Its façade faces Building 33; it only conserves the central lintel where Pájaro-Jaguar IV is observed, with its center, dialoguing with one of its warriors. Regarding the other lintels, one was stolen by Maudslay in 1882 and the other is in the National Museum of Anthropology.

Hieroglyphic step of Building 44: Buildings 43, 44, 45 and 46 limit this complex to the north, and their facades face the river. The importance of Structure 44 is highlighted by the presence of stelae 14, 17, 21, 22, 23 and 29, located in front of this building. It is calculated that the construction of this building occurred during the period of Escudo Jaguar I. There is a hieroglyphic step located at the central entrance of this building, although it is currently protected with a stone box.
