Musée de la Poste in Paris

You're standing at the Musée de La Poste, the museum of France's postal service, La Poste. You're right by Montparnasse station here, in the 15th arrondissement of Paris. Take a look at the front of the building. That façade was designed by André Chatelin when the building went up between 1969 and 1972. A museum about letters and stamps in a modern block like this one? Not what most people expect.
