Architect's model for the proposed World Trade Center on the East River
http://en.wikipedia.org/wiki/Construction_of_the_World_Trade_Center#Original_plans
120 Wall was the first location choice for the WTC complex.

120 Wall would have been flanked by 2 giant slabs, one vertical & the other expressing the horizontal.
Curiously, either WTC location would have ended up with 2 big open squares.
