This complex marks the symbolic and religious importance that establishes it as the center of the ancient city, with the Building of the Niches. Its area is formed by 14 monumental structures, five of which are ball games and nine monumental buildings. It also has two emblematic structures that, due to their location, reflect the cosmovision of the inhabitants of this site.

This structure has worldview markers that correspond to the exploits of gods, mythical ancestors or recent ancestors; landmarks that enable mediation and communication with the sacred; indicators of ethnic or social identity and, finally, markers that establish and reaffirm their idea of a “sacred geography”.

In this area some of the buildings still have remains of original blue and red paint. It is worth mentioning that one of the new conservation works was carried out in Building 11, which is part of a ball game adjacent to the Nichos building. During its occupation, the structure underwent four remodeling works that covered and protected the mural painting from the passage of time, until its discovery in 1989. However, due to climatic and environmental conditions, the mural painting suffered severe problems. Therefore, in 2012, INAH specialists elaborated a project that aims to preserve the mural painting in the long term through its reburial. For the time being, in order to disseminate the only testimony of the mural painting that covered the ceremonial area of El Tajin, a replica of the mural was made in situ, which is what can be seen today.
