Tenochtitlan was built on a marshy island in Lake Texcoco in what is now southern Mexico. Because no one else coveted the area, the Aztecs were allowed to settle there. It wasn’t an ideal spot to construct a city at first, but the Aztecs eventually built up islands where they could produce food. The sea also served as a natural shield against other cities’ assaults.
