We are going to pick the best example for traditional culture in southwest México: the state of Oaxaca.
During the 1800s, Oaxaca developed a refined sense of art, influenced by prehispanic cultures such as the Zapotecs, who built the impressive city of Monte Alban, one of the most spectacular archeological sites of southwest México during the Mesoamerican times.
