On the west side, on top of the platform, sits the building that was the dwelling of the ruler. On the eastern side is the stairway, which reaches 4 meters in height above the platform; it has a double alfarda topped by cubes at the top. The whole construction is formed by basalt blocks glued with lime mortar and pulverized tezontle. The building was covered with a layer of stucco painted red.

Marker ring: This element indicates that in Chimalhuacán the ball game was practiced.

Sculpture of snake and anthropomorphic figure: They correspond to the substructure of the Palace (1200-1430).

In the staircase of the Palace, the alfardas and the cubes that finish them off can be appreciated.
