Perhaps Mexico’s grandest set of ruins, which include the world’s third tallest pyramid. Not built, contrary to popular belief, by the Aztecs, Teotihuacan was built hundreds of years before they arrived on the scene, and then mysteriously abandoned. Since then archeologists have had an awful lot of fun with the site. Many would say too much fun, restoring huge amounts of the site. The further you go from the Ciudadela the more is restored.
But how to tell what’s what? Well, the archeologists (vandals!) kindly left little stones in the cement they used to show where they had rebuilt. Click on ‘Read more’ to see some photos.
As you can see in the images below, one photo clearly shows the little stones in the cement where repairs have been made. The other is all original. You can also see in the repaired photo, the alabaster that all the stones used to be covered with. This is original.
In the image above you can see where the remains of an original wall have been built up. And below, some original wall paintings. Although they are often remounted on repaired walls too.
