At the foot of the entrance to the temple there is a huge forked tongue. To the east of the door we can appreciate the beautiful sculpture of the head of a serpent of warlike character on which rest the remains of the statue of a warrior, and to the west there is another sculpture in the form of an enormous pedestal, symbolizing a tlalpanpanhuehuetl (war drum), on which are the remains of the sculpture of another warrior: apparently, both pieces functioned as standard bearers. As in other Mexica buildings, the orifice of the serpent's mouth served as the entrance to the enclosure, with the difference that the temple of Malincalco added a special drama thanks to the fact that the enormous forked tongue of the serpent served as an entrance mat.

The interior of the temple is extraordinary. On the floor there is a kind of bench that surrounds the space in the form of a hemicycle, where two eagles are located and, between them, an ocelot. In the center of the enclosure there is another eagle with the same attitude as the previous ones and, behind it, a round hole where possibly the heart of the sacrificed was deposited. In general terms, this temple served as a stage to carry out the initiation ceremonies of the eagle and jaguar warriors, hence the predominance of sculptures of these animals. However, there is a third figure that is of fundamental importance here: the serpent.

It is a truncated pyramid oriented to the west, with a single staircase with alfardas. It is built of stone and covered with a layer of stucco.

This interesting construction covered with stucco consists of two rooms: the first rectangular and the second circular. At the entrance of the first one there are a pair of pillars that supported the lintels, the façade and the roof. Around this room, which was originally decorated with a mural painting, there is a wide bench or platform that runs along its east, west and north sides, where it divides in the center to form the entrance to the second enclosure: the circular one, in which, like the previous one, there is an altar badly destroyed by fire. Both to the east and west of these temples it is possible to notice remains of rooms that must have served as residence. It is believed that the cremation festivities of the members of the military organization who died or were taken prisoner on the battlefield were held inside them.

It is a large rectangular semi-monolithic structure with the characteristics of a platform. In the center of this large room are two elongated monolithic bases in the form of sarcophagi, which served as a base for the wooden pillars to support the roof. It is believed that in this place the netonatiuhzaualiztli, that is to say, the great feast of the Sun, was held every 260 days.

It is very small, its diameter barely exceeds 2 meters, and stands on a platform. Its plan is circular and made of masonry. It was almost completely destroyed.

It was under construction when the Spaniards arrived, which is why it was never finished. Apparently, the intention was to build a round monument. Some of the flint chisels used for its construction were found among the rubble.

In the highest part of the hill of the idols, on an artificial platform, there are pyramidal foundations, remains of rooms and walls. In this site a stone sculpture of Ehécatl-Quetzalcóatl, god of the wind, was found, as well as funerary urns in the form of a cylinder.

It is a small quadrangular room located in the upper part of the monolithic temple; it is estimated that it must have been used as a room for a priest.

They are the remains of another small habitational foundation to which the monolithic staircase located on the west side of the temple leads.

Rectangular structure with remains of very narrow walls, which at some point were walled up. It is considered that it could have been used as a granary or weapons store.
