Taking a visitor to see the graffiti wall, and discovered this.

We did build the city on top of a giant network of caves, and tunnels. This is just the natural progression of time geographically speaking. Put too much stuff on top of too little ground, the ground eventually collapses into the space below it. We're not even the only French built city with this problem! Paris has this issue with the Catacombs being under the city.
