Los Guachimontones represents the largest discovered site from a culture that once flourished in the Tequila Valley region between 300 BC-900 AD/CE.

The reconstructed site and accompanying Interpretive Center were created to help people learn about the lost culture.

The Teuchitlan culture is known for its distinct circular, step pyramid structures (described as looking like a layer cake or bee hive) consisting of a round central altars (a style that is called “Guachimontón”) surrounded by a circular patio space, and a circular banquette on which sits four to sixteen rectangular or square platforms. The connection between the Teuchitlan culture and the larger, older Shaft-Tomb culture (500BC-400CE) is blatant.  Shaft-tombs are found directly underneath the platforms in the guachimonton structures.  Though whether the shaft-tombs came first at the structures or not is still under investigation.

Excavations at other Teuchitlan sites have shown similar constructions, and that a post hole would have been located in the central altar (or sometimes central space if the altar is lacking) during rituals. Ceramic dioramas of the full guachimontons, unique to the Mesoamerican region, from shaft-tomb and guachimonton site excavations, display  pole ceremonies that the Teuchitlan community members performed all across their culture. Often they display where a leader would climb the pole as a devotional act to their god. However feasting, musical instruments, and even burials are also depicted in these dioramas.

American archaeologist Dr. Phil Weigand and his wife Celia Weigand discovered the Los Guachimontones site in 1969. Dr. Weignad, through drive-by and regular archaeological survey recorded over 200 guachimontones around Western Mexico, the majority being in the Tequila Valleys area in highland Jalisco.

While the connection between the Teuchitlan culture and the greater Mesoamerican pantheon is unclear, there is evidence of some old gods worship. These possible connections are being studied primarily by the Colegio de Michoacan and they run the Los Guachimontones labs.
