It is the most emblematic building of the indigenous city Xochicalco. Mainly consists of 8 feathered snakes arranged in different positions, distributed 2 on each facade, they are adorned with elements from cultures from Oaxaca, Veracruz and the Mayan area. Between the undulating bodies of three of its façades, an elegant Mayan priests can be seen in a meditation position, and on the west façade, inside the body of the snake a calendar adjustment was represented, the representation of a glyph of a date can be seen (10 House Day) held by one hand, and another pulling a date to replace it (11 Monkey Day) which is interpreted as a calendrical correction that would start a new account in the year 6 Cane.

This calendrical adjustment event was probably attended by towns governments that had a certain relationship with Xochicalco to unify the counting time way, all this during a total eclipse of the sun, which was predicted by the Xochicalcas priests. Possibly this temple is one of the most important reasons for inscribing the Xochicalco Archaeological Monuments Zone on the World Heritage List.
