PPG Place is a complex in downtown Pittsburgh, Pennsylvania, consisting of six buildings within three city blocks and five and a half acres. PPG Place was designed by architects Philip Johnson and John Burgee. The project was started by PPG Industries (formerly Pittsburgh Plate Glass Company) to serve as the company's headquarters, after being based in Downtown Pittsburgh since 1895. (Source: Wikipedia)
