The town of Zaachila, 15 kilometers south of the city of Oaxaca notable for its gastronomy and the archaeological site. One of the most authentic markets in the area and is held on Thursdays and brings together flavor and tradition. Zaachila was also a town that played an important role during the Classic Period of Zapotec culture. Evidence of this are the two tombs that are part of the city, built in a manner similar to those constructed during the period of Monte Albán's greatest prosperity. On the last Monday of July takes place a colorful festival at the archaeological zone “el cerrito” to honor the Goddess of Corn.
