Monte Alban was an ancient Zapotec city that is now in Oaxaca, Mexico in the heart of what has come to be called Mesoamerica. It was first constructed around 500 BC and was inhabited through around 750 AD. Around this point, the city was abandoned, but was briefly reoccupied on a minor level at various points up through the Colonial period.

The hilltop area of Monte Alban has now been restored, and the archaeology site is now a major tourist destination. The site is now located around 9 kilometers outside of Oaxaca City, and there are regular buses and taxis that go there. If you are bold enough, you can walk to Monte Alban.
