City on Water
How did the Aztecs build a great city on a lake?

Picture a city more crowded than most cities in Europe at the time — sitting right in the middle of a lake. Not beside it. In it. The Aztecs called it Tenochtitlan, and it shimmered like something out of a dream. So how do you build a great city on water? You start, oddly enough, by being told to.
The story the Aztecs told goes like this: their god promised they would find their home where they saw an eagle perched on a cactus, eating a snake. After years of wandering, they spotted exactly that — on a soggy little island in the middle of a lake. Not the comfiest real estate. But a promise is a promise.
