Do you know why the Paris skyline was devoid of skyscrapers, I mean the prewar, proper Paris skyline? Do you know why they stuck all those glass and steel monstrosities out in La Defense, so far from the city center? Yes, there’s aesthetics, a sense of continuity and civic pride…not like that architectural mongrel called London. But the truth, the logical, practical, reason for keeping Paris free from American-style monoliths, is that the earth beneath their feet is simply too tunneled to support it.
