Abstract view of Midtown Manhattan architecture

I have no idea what this structure is - we were walking across Midtown Manhattan towards Queensboro Bridge and stopped to apply suncream in its shade! There are benches beneath it and it is right in front of an office block. The tall thin tower that you can see in the circle is 432 Park Avenue (which you can pretty much see from anywhere in Manhattan!).
