Owing to the region’s rich volcanic soils and strategic location, Náhuatl-speaking Indians once developed a complex civilization in Puebla; today, many monumental ruins can be found throughout the state. Puebla is also the home of Mole Poblano, a traditional Mexican dish. Today, automotive and textile production are Puebla’s main manufacturing industries. Manufacturing constitutes the largest percentage of the economy at about 24 percent. Service-based companies account for 19 percent, followed by trade activities at 18 percent, finance and insurance companies at 18 percent, transportation and communication companies at 8 percent, agriculture and livestock production at 8 percent, construction at 4 percent and mining at 1 percent.
