The Pre-hispanic world of Mexico was the most important of America. Made up of different civilizations that built magnificent cities and ceremonial centers in their dominions. With the arrival of the Spaniards in the 16th century and the conquest of these territories, many of the cities began to be lost and others disappeared. However, that which has been inherited is immense and we can still visit a great deal of places, without taking into account what is still below earth. Among the most important civilizations are the Mayas, great ingenious constructors (Palenque, Uxmal, Chichen-Itza, Comacalco and Tulum). The Totonacs (The Tajín in Veracruz). the Nahuas (in Xochicalco, State of Morelos). The Teotihuacans (from Teotihuacán in the State of Mexico). The Nahuas (in Xochicalco in the State of Morelos), the Teotihuacans (in Teotihuacán in the State of Mexico) and the Toltecs (in Tula in the State of Hidalgo).
