Guiengola

This is a very important Zapotec Ancient City on a mountain top overlooking the city of Tehuantepec on the Isthmus of Oaxaca. Famous battles against the Aztecs where staged here as the invaders wanted to control the pass to Central America that the Zapotecs held. Under the great Zapotec king Cocijoeza the locals resisted but later the king married the daughter of the Aztec king Ahuizotl named Coyolicatzin and then formed an alliance until the European conquest.
This site is hard to get to but worth its early climb, mainly due to the fierce hot sun in this part of Oaxaca.
