Peralta is located on Abasolo, 21 km from Pénjamo. It developed between 300 and 700 CE, at the time that Teotihuacan was declining and Tula was rising. According to archeologists, the city declined and collapsed due to the overexploitation of the surrounding deciduous rainforest and it was abandoned around 900 CE. The site occupies 150 hectares divided into a center with five surrounding settlements. The most important structure is called the "Patio Hundido" (Sunken Patio), whose name comes from the four pyramids that are at the corners. Another important building is the La Mesita (The Small Table) or Recinto de los Gobernantes (Governors' Precinct). It has a large plaza which is considered to have been the main square for the city. Among the walls and other structures a semicircle dedicated to the Danza de Voladores has been discovered.Quintanar Hinajosa, pp. 23–24
