This vast building squats heavily over Park Avenue and Grand Central Station; the cars from Park Avenue run through tunnels in the sides of the building, and trains rumble along in their own tunnels far below.

It was originally known as the Pan Am building, before Metropolitan Life Insurance bought it for $400 million in 1981. The developers were able to make the building large and bulky only by buying the air rights over historic Grand Central Station, which is now mostly hidden by the MetLife building.
