How long could a city last if it were completely underwater?

Let's say there is a city, about the size of New York City, that is made only out of stone, steel, and glass. This city would be completely underwater. Assuming no humans are alive in this city, how many years would it take for the city to be destroyed fully?

(Edit 1) By destroyed fully, I mean so it is unrecognizable as a city but rubble remains.
