City of Puebla de Zaragoza coat of arms, Mexico

Puebla de Zaragoza (Spanish pronunciation: [ˈpweβla]; Nahuatl languages: Cuetlaxcoapan; Mezquital Otomi: Nde'ma), formally Heroica Puebla de Zaragoza, formerly Puebla de los Ángeles during colonial times, or known simply as Puebla, is the seat of Puebla Municipality. It is the capital and largest city of the state of Puebla, and the fourth-largest city in Mexico, after Mexico City, Monterrey, and Guadalajara. A viceregal era planned city, it is located in the southern part of Central Mexico on the main route between Mexico City and Mexico's main Atlantic port, Veracruz—about 100 km (62 mi) east southeast of Mexico City and about 220 km (140 mi) west of Veracruz. The city was founded in 1531 in an area called Cuetlaxcoapan, which means "where serpents change their skin", between two of the main indigenous settlements at the time, Tlaxcala and Cholula. This valley was not populated in the 16th century, as in the pre-Hispanic period this area was primarily used for the "flower wars" between a number of populations. Due to its history and architectural styles ranging from Renaissance to Mexican Baroque, the city was named a World Heritage Site in 1987. The city is also famous for mole poblano, chiles en nogada and Talavera pottery. However, most of its economy is based on industry. Being both the fourth-largest city in Mexico and the fourth-largest metropolitan area in Mexico, it has a current population of 3,344,000 people, and the city serves as one of the main hubs for eastern-central Mexico. Students from surrounding states attend its prestigious universities, such as BUAP, UDLAP, Ibero, among others. The city also excels in industry, having the world's largest Volkswagen factory outside Germany, located in the Municipality of Cuautlancingo and an Audi plant in San José Chiapa. As a result, many suppliers to Volkswagen and Audi assembly plants have opened factories in the metropolitan area of Puebla.
