There is a deep history associated with these sites, which show incredible design and architecture. One great example is The Pyramid of the Sun, which is the largest building in Teotihuacan. Experts believe that the pyramid was built around 200 CE. The site is stationed along the Avenue of the Dead, which is directly in between the Pyramid of the Moon and the Ciudadela.
