On this leg you'll be arriving at what was previously known as Villa de San Jerónimo Doctor but is now called Ciudad Ixtepec. The name "Ixtepec" is derived from Nahuatl and roughly translates to either "view of the mountain" or "face of the mountain."Its name was Iztepeque until 1935, when it was officially changed to Ciudad Ixtepec (Ixtepec City). The founding of the city was most likely in the 16th century as a Zapotec settlement shortly before the Spanish Conquest. It remained an indigenous community until the 19th century, with its economy based on subsistence farming. In the early 20th century, the community grew in economic importance as its location made it attractive to foreign investment with the building of the Pan-American Highway, originally as a rail line.
