The temple sits inside La Ciudadela, a vast sunken plaza that could hold thousands of people for ceremonies. Its walls are decorated with serpent heads and seashell motifs, representing water, fertility, and cosmic order. When archaeologists excavated the site, they discovered hundreds of human sacrifices buried beneath the steps, likely warriors offered to consecrate the pyramid. This makes it one of the richest archaeological finds in Mesoamerica.
Tip: Bring binoculars or use your camera zoom. The serpent heads are smaller than they appear in photos, but the details are mesmerizing up close.
