Paul Andreu was a French Architect who designed many magnificent buildings and airports, including the Grande Arche at La Defense in Paris. This imposing monument was built to commemorate the 200th anniversary of the French Revolution and was initially begun by the Architect Johan Otto von Spreckelsen; however, Spreckelsen eventually resigned and Andreu finished the project in 1989 with enginner Erik Reitzel. I really like the dominating presence of this design, and the optical effect of the sky being visible through the archway is quite breathtaking.
