The archaeological park of Teotihuacan is under threat from development pressures.
In 2004, the governor of Mexico state, Arturo Montiel, gave permission for Wal-Mart to build a large store in the third archaeological zone of the park.
According to Sergio Gómez Chávez, an archaeologist and researcher for Mexico's National Institute of Anthropology and History (INAH) fragments of ancient pottery were found where trucks dumped the soil from the site.

More recently, Teotihuacan has become the center of controversy over Resplandor Teotihuacano, a massive light and sound spectacular installed to create a night time show for tourists.
Critics explain that the large number of perforations for the project have caused fractures in stones and irreversible damage, while the project will have limited benefit.
