It was restored in 1954, when Florencia J. Müller and César Lizardi Ramos began their explorations in Huapalcalco. It is an open space, with a pyramid located to the east and a pyramidal annex to the north side. In the central part of the square there is an altar-stele.

Main pyramid: Its facade, oriented toward the west, has a stairway of eight steps delimited by smooth alfardas; these are deployed from a plinth, which runs along the entire front of the monument. It has several superimposed constructive stages. In the architecture of Huapalcalco the Teotihuacan influence of boards and slopes is noticed.

Altar-stele: It is an irregular stone without working, reason why César Lizardi Ramos called it “altar and presumed stele”.
