This square is named after the Astor family, who built an early New York fortune on beaver pelts (check out the tiles in the wall of the Astor Place subway platform) and lived on Colonnade Row, just south of the square; four of the original nine marble-faced, Greek Revival residences on Lafayette St still exist. The large, brownstone Cooper Union, the public college founded in 1859 by glue millionaire Peter Cooper, dominates the square – now more than ever – as the school now has its first new academic building in over 50 years, a striking, twisting, nine-story sculpture of glazed glass wrapped in perforated stainless steel (and LEED-certified, too) by architect Thom Mayne of Morphosis.
