First of all, pretty much all of the indigenous city is gone. All of the bulidings are from colonial or posterior times. And second, cities are built on water all the time (Vence, Suzhou, Amsterdam) And they managed to subsit just fine. The problem came when all the infrastructure used by the natives was destroyed and the solution used was to drain the lake, which has only led to a massive ammount of problems.
