At the Great Plaza's west end rises a pyramidal substructure on top of which lie the remains of a ruined temple. It is known as Temple XI and it remains unexplored to this day. The Plaza's northern limit is marked by a broad stairway which once gave access to it from a lower platform. Finally, on the south side, covering more than half the total length of the Great Plaza, lies a very large platform, the result of many modifications carried out on the flank of a large hill. On this platform rise four structures known as the Temple of the Inscriptions, Temple XII-A, the Temple of the Skull and Temple XIII.
