The story
Take a look up at the golden glow of the Winged Victory, shimmering high above the constant hum of Paseo de la Reforma. This is the Ángel de la Independencia, the most beloved landmark in Mexico City. But as you stand here, I want you to look not just at the statue, but at the stairs leading up to its base.
They tell a story that most people walk right past without realizing. When this monument was inaugurated in 1910 by President Porfirio Díaz to celebrate a century of independence, it looked very different at ground level. Back then, there were only nine steps.
Today, there are fourteen. You might think the monument is growing, but the truth is far more dramatic: the city around it is sinking. To understand why, we have to look back centuries.
This entire valley was once the Great Lake Texcoco. When the Spanish arrived and eventually drained the waters, they were left with a massive basin filled with soft, sponge-like volcanic clay. As Mexico City grew into a sprawling metropolis, we began pumping massive amounts of water from the underground aquifers to sustain the population.
As that water is removed, the clay layers compress like a dried-out sponge, and the ground simply gives way. But the Angel is different. Its engineers knew the soil was treacherous, so they didn’t just build on the surface.
They drove massive steel piles nearly fifty feet into the earth, anchoring the monument into a layer of solid, prehistoric bedrock known as the "capa dura." This created a fascinating geological standoff. While the streets, the sidewalks, and the surrounding office buildings sink along with the settling earth—sometimes by as much as a foot every year—the Angel stays exactly where it was placed in 1910.
It is a fixed point in a shifting world. Every few decades, the gap between the sinking street and the stationary monument becomes so great that the city has to add another set of stairs just so we can reach the entrance. As you walk around the base, notice the different textures of the stone on those lower steps.
They are the physical record of a city’s struggle with its own geography. The Angel isn’t just a symbol of freedom; it’s a golden yardstick, measuring exactly how much of the ancient lakebed is disappearing beneath our feet. It remains a steady, shimmering guardian, even as the very ground of Mexico City continues its slow, inevitable descent.
