This is the front of the Mediopadana railway station in Reggio Emilia, Italy. It is foreshortened in the picture. The architect/engineer is Santiago Calatrava of Spain. Check Google for pics of his other spectacular work. The photo was taken by Antonella Sacconi. Prints can be purchased on her fotoblur page. While the picture looks gray, you are actually looking at steel painted white. Enjoy.
