At the base of the towers, Yamasaki used implied pointed arches—derived from the characteristically pointed arches of Islam—as a transition between the wide column spacing below and the dense structural mesh above. (Europe imported pointed arches from Islam during the Middle Ages, and so non-Muslims have come to think of them as innovations of the Gothic period.) Above soared the pure geometry of the towers, swathed in a shimmering skin, which doubled as a structural web—a giant truss. Here Yamasaki was following the Islamic tradition of wrapping a powerful geometric form in a dense filigree, as in the inlaid marble pattern work of the Taj Mahal or the ornate carvings of the courtyard and domes of the Alhambra.
Interesting. Now doesn't this put a unique twist on the current 'Ground Zero Mosque' controversy?
PS. The title of the article is stupid and clearly *NOT* the reason Bin Laden attacked the U.S.
