Is The Empire State Building An example of obelisk shape?

The Empire State Building is an example of a setback skyscraper, not an obelisk. An obelisk is a tall, four-sided, tapering monument, usually made of stone. The Empire State Building, on the other hand, is a skyscraper with a steel frame and a limestone and granite façade. It has a rectangular base and tapers slightly towards the top, but it is not an obelisk.
