This plaza represents the axis of the city and is formed by six structures arranged around it. Most of them were built during the Late Classic and Terminal Classic periods.

Structure I: Structure I is the second largest building in Calakmul, and is located southeast of Structure II. It is a building that, in its previous constructive stage, presents masks that flank its stairway. This building is associated to a solar cult due to its orientation, in addition to not being in front of any object of greater size, natural or artificial, that obstructs the visual in straight line between the horizon and the sunset.

Structure II: To the south of the Central Plaza is located the most important building in Calakmul, Structure II, which is oriented to the north. Structure II evolved and gained height and volume; some of its remodeling was decorated with masks; its buildings became more complex and increased in number until it housed six structures on its summit. Its construction dates back to the earliest period of Calakmul's occupation; during the Early Classic (between 250 and 600 A.D.) the building was modified on two occasions: in the first, a new covering was added to the front portion of the structure; later, the construction of four buildings on the upper part responded to a change not only in the power structure, but also in new stylistic concepts in Maya architecture.

At the base of Calakmul's Sub II-c structure, two masks of 4 m high and 5 m wide were placed, delimiting a stairway that gave access to a passageway covered with a barrel vault, with a lowered arch. The passageway is located in the central part of the architectural massif that forms Structure II.

Structure IV

Structure VI: Structures IV and VI, located to the east and west of the plaza, form an early E-type complex. This type of complex had a layout that allowed observing the sunrise at different times of the year, mainly solstices and equinoxes. Two structures are necessary to form an E-type complex. A not very high building, from where it is possible to observe the sunrise, in this case Structure VI, at a distance in which you will have a perfect view of the second building.
