Toward the end, Zaachila was conquered by Mixtecs, who occupied it until the arrival of the Spanish conquistadors. The name "Zaachila" is derived from the term "House of Zaachila", a reference to the pre-Colombian Zapotec king Zaachila Yoo. The site is part of the contemporary town of Zaachila, where one can still observed pre-Hispanic traditions and customs, and attend the famous tianguis held each Thursday.
