Pirámides de Teotihuacan
Visit the City of the Gods and Scale an Ancient PyramidWhile it's not in Mexico City proper, the sacred pre-Hispanic city of Teotihuacan is close enough–about 30 miles– for an easy day trip if you're interested in architecture, archaeology, and indigenous history. The site's primary structures, the Temple of Quetzalcoatl and the Pyramids of the Sun and the Moon, have been designated by UNESCO as World Heritage Sites, and it is possible to explore the pyramids–and even climb them–either independently or with a guide. After ascending nearly 250 steps on the Pyramid of the Sun, you'll have a greater appreciation for these ancient structures and the civilization responsible for having built them. In addition to the pyramids, an on-site museum documents the history of the so-called "City of the Gods," and displays archaeological finds, including pottery, bones, and other important objects.
Teotihuacan, Mexico City
This view is from the top of the "Moon Pyramid" in Teotihuacan looking out over a 2 kilometer stretch that's been excavated. It's a common misconception that the Aztecs built these structures, but they actually discovered and inhabited them much later.
