Two+Prudential+Plaza,+N+Bai

The sight of Two Prudential Plaza, a 1990s modern art skyscraper located in the windy city is enough to take anyone’s breathe away. Upon its completion it was seen as an architectural feat; standing 995 feet tall and made entirely out of reinforced concrete, the tallest of its kind at that time. One of its most influential designers, Stephen T. Wright was honored with eight awards for his masterpiece, including the prestigious, Best Structure Award 1995. Today it functions as an office building out of which many local Chicago radio stations are based.
