Brussels underwent massive urban development, mostly before and after the 1958 World’s Fair, which went beyond laissez-faire and became laissez-aller. The city was dug up from one end to the other, torn down and filled with high-rises. Underpasses and overpasses were built, train tracks and stations placed underground. Skyscrapers built in sculptor's parks. "Progress" was the deity to which urbanism was sacrificed.
Urban planners named it "bruxellisation".
An ongoing project.
