alt Hacker NewsSo, perhaps a dumb question, but the article mentions that 14 steps have been added to the base of the Angel of Independence monument, and the Wikipedia article mentions the same things:
> Originally, nine steps led to the base, but due to the sinking of the ground, an ongoing problem in Mexico City, fourteen more steps have been added.
So why didn't the monument itself also sink? Does it have piles going down to bedrock or something?

Also from wikipedia: ... "The commission determined that the foundations of the monument were poorly planned, so it was decided to demolish the structure."
So yes, it has an engineered foundation, a double-engineered foundation. The roads around it almost certainly do not. So it is plausible that the monument is not sinking as quickly.
thousands of wooden piles to create a foundation with the first one even failing and the foundation being reconstructed
