The third building, and one of Andreu’s most famous, is the Charles De Gaulle Airport terminal 1.  The modernist terminal was opened in 1974, and has since been a major photography spot in Paris. It was one of Andreu’s first major works, and he went on to design many more airports. Andreu was in charge of other terminal designs in the airport, but unfortunately Terminal 2E partially collapsed in 2002, resulting in 4 deaths. The escalators are the glass tubes in the pictures above, and deliver passengers from upper level arrival gates to the lower level exit in style. I really like the circular design of the terminal, and it seems like a very open, abstract piece of architecture.
