PPG Plaza

PPG Place is defined by a forest of two hundred and thirty-one glass spires that rise above a six-building complex. Designed by architects Philip Johnson and John Burgee, the headquarters for PPG Industries—formerly the Pittsburgh Plate Glass Company—covers five and a half acres in the heart of downtown. Completed in nineteen eighty-four, the project uses nearly one million square feet of reflective glass to reinterpret Gothic forms through a modern lens, creating a silhouette that critics often call the crown jewel of the city skyline.
