Separated from the Great Temple, on the north and south sides, there are small altars (two on the north and one on the south). Their peculiarity lies in the fact that they are associated with figures identified as Xiuhcoatl (fire serpent). The heads of the reptiles are carved in stone and emerge from a coiled body of masonry. They accentuate the details of the fangs and emphasize the crest in the form of a volute topped with protuberances. The altars of the Xiuhcoatl correspond to the type of platforms defined as momoztli, that is, small temples located at the foot of or associated with the main temple where ceremonies were held or offerings were placed.
