Mexico City
The world has quickly become a world of cities. Huge metropolis areas have taken over the landscape of the urban population. There are few cities that have the sheer size of Mexico City. But there’s much more to this city than sheer size. The top 100 travel sites all have their own recommendations for this amazing city, but even their guidance can’t possibly cover the wealth of things there are to do and see in this great city. The city’s main square, known as the Zocalo, actually stands on top of ruins of the indigenous city that once was home to hundreds of thousands people. Mexico City takes weeks worth of exploration to really appreciate and understand. Get out there and explore it.
