Los Guachimontones is one of several dozen Teuchitlán Culture sites within the Tequila Valleys, though it is by far the largest site in terms of both the number and size of its ceremonial buildings. These buildings, called guachimontones (singular, guachimontón) after the site name, are bulls-eye shaped buildings consisting of several distinct architectural elements that constitute a whole structure. These unique buildings are found primarily in the Tequila Valleys with other examples found in northern Jalisco near Bolaños, Guanajuato to the east, and Colima to the south.
