- The diagonals completely block the view from two windows on
each floor. Ironically, a rental agent has transformed these
"blocked" windows into something of a status symbol -- it actually
costs more money to rent from these rooms!
- In 1997, the John Hancock Center was remodeled, and half of
the 94th floor's southern windows were replaced with screens.
Tourists can visit the "Skywalk," as it is called, and breathe the
outside air and hear the noise of the city below.
Offices occupy the lower floors of the 100-story
skyscraper, and apartments are located on the upper floors of the
building. Additional facilities include restaurants, health clubs, a
swimming pool, and even an ice-skating rink.
