Rockefeller Center

Actually a 22 acre "city within a city", Rockefeller center was built by John D Rockefeller Jr at the height of the Great Depression. It was the US's first retail/entertainment/office center of 19 buildings and declared a National Landmark in 1987. Most interesting in this space is the GE Building offering a Top of the Rock observation tower (actually taller than the Empire State Building's) and Rockefeller Plaza.

Wollman Rink

This ice skating rink is set in the heart of Central Park and is a star player in numerous Hollywood movies. Located at 59th Street and 6th Avenue, it has spectacular views of the skyline of Manhattan.
