This magnificent Art Deco, 70 story skyscraper, a/k/a 30 Rock, was built in 1933. It is the centerpiece of Rockefeller Center, a 19 building, 22 acre complex in Midtown Manhattan. It is the home of the NBC television network, contains NBC Studios, a spacious observation deck on top, the Rockefeller family office and much, much more. Best viewed enlarged (you can see the Wisdom frieze featured a few days ago when seen large).
I remember going here as a little kid and being amazed by the whole complex of structures. Hard to believe this was built so song ago. I like this iconic viewpoint.
