Introduction

It is hard to believe that aliens weren't involved in the construction of many ancient structures (right, Luke?), and this is certainly the case for the 7 modern wonders of the world! We have kicked off a new mini-series that is looking at the engineering and history behind the 7 modern wonders of the world, starting with Chichen Itza in the heart of Mexico. We discuss how it is thought to have been built, the changes that have taken place over the years, what caused the city to be abandoned, and anything else you could want to know about this world wonder.
