Mexico City’s center square is about a mile or so from what the Aztecs considered to be the center of the universe. Even so, the Zocalo (named for the base of a celebratory column that never was built) largely occupies the main ceremonial grounds of the Aztec city of Tenochtitlan, over which modern-day Mexico City rests. The east side of the Zocalo is framed by the National Palace, home to Mexico’s government. As such, the square—the largest in the city—is a frequent venue for not only festivals, tourists and political rallies but also protests and demonstrations.
Located well within the tropical zone, Mexicans — like the Aztecs — discovered long ago that the only way to escape the heat and humidity is to move up. Mexico City rests on a plateau roughly a vertical mile above sea level. While this mitigates the tropics’ enervating climatic effects, it comes at a price: basic transport costs within Mexico’s mountainous core territories are among the highest on Earth, complicating every type of economic and cultural development imaginable.
