Guachimontones
The Guachimontones archaeological site, just outside modern-day Teuchitlán, Jalisco, is the largest and most complex site within the Teuchitlan tradition. The center of the ancient village was occupied by three circular areas, each of with a multi-level circular step pyramid at its center. There are a total of 10 such "Circles" within Teuchitlan, along with four rectangular plazas and two ballcourts among many other smaller structures.
The circular pyramids are thought to be cosmograms, representing the mythological structure of the universe, and the circular poles that were set into their center the Mesoamerican world tree. Based on the many ceramic tableaus that have been recovered, it is similarly thought that volador ceremonies were conducted from the pole.
