funny, but even if i really love the shape of Freedom tower, for me the twin towers looked more impressive...
But in one hand it's normal:
first, there were TWO twin towers: it looked more massive as the two buildings were very close to each other.
Then, many buildings of south manhattan were not yet built in 2001, like the beekman tower, or the WFC... the twin towers dominated a skyline more reduced than now.
And finally, because of their shape, each twin tower's volume was 1.5 times bigger than Freedom tower...
What about your minds ?
At least, everybody in NY seems to love the new design, whereas the twin towers never managed to seduce ...
