Museum of the Teotihuacan Culture

The Museum of Teotihuacan Culture lies within the archaeological site of Teotihuacan, which is south of the Pyramid of the Sun and it shows the developmental stages of Teotihuacan. Within this city there are bits and pieces that have been salvaged from the many on-site excavations. The museum also features a to-scale model of the archaeological site where the Sun Pyramid is seen through real glass. It's really worth the short walk to get there and have a chance to see it. You can't miss it if you're in Teotihuacan, it's very interesting and admission is free, you just have to present your proof

This is one of the most amazing museums in Mexico City.
