Oaxaca: (Oaxaca state)
Considered the most colonial city in Mexico, Oaxaca was founded by Hernan Cortes in 1529. It sits in a valley surrounded by the towering Sierra Madre del Sur. Built in the shadow of the ruins of the Mixtec and Zapotec civilizations, it is a stunning mixture of colonial and Indian influence.
Many of Oaxaca's buildings are constructed of an unusual greenish volcanic stone that takes on a golden tone at sunset. Others are painted bright turquoise or pink. B
