Still partly under excavation, the Atzompa ruins sit on top of Cerro El Bonete hill 2km above Atzompa village. The site flourished from AD 650 to 850 and provides spectacular views to Monte Albán, 4km south, as well of Oaxaca and of the Valle de Etla stretching away to the north.
Three ceremonial plazas, one ball court and the remains of two large residences have been exposed to view. A specially intriguing feature is the reconstructed pottery-firing oven on the north side – identical to ovens still used by potters in modern Atzompa.
