6. The last work from Philip Johnson I chose to highlight is the PPG Place. It is located in Pittsburgh, PA and is said to be one of the jewels of Pittsburgh’s skyline. This building is the home for numerous businesses and firms. It looks like it is completed covered in shimmering glass. Essentially 19,750 pieces of glass is glazed over the materials of the building. Philip Johnson was the architect for many well-known and impressive skyscrapers, but I would say this is one of my favorites from him. Altogether, the entire complex is over 5 acres and has a plaza located in the front where they host events for the public, very similar to how OKC people visit the Devon Tower and Meridian Gardens downtown. To me, it looks like a modern day castle.
