Tlacolula
Tlacolula lies in the eastern arm of the Oaxaca valley, a fertile corridor between the central highlands and the route towards Tehuantepec. Nearby Mitla became an important Zapotec religious and artistic centre after the decline of Monte Albán. Its market served trade along the eastern valley. Under Spanish rule the market was moved to Tlacolula, giving the town a prominent place in the exchange of goods across the valley.
