Stazione Milano Centrale is the main station in Milan and has the most passenger traffic of any train station in Europe. It is large and very busy, connecting Milan with many of Italy and Europe's great cities.
The station was officially inaugurated in 1931 to replace the older central station (built 1864). Its reconstruction coincided with Benito Mussolini becoming Prime Minister. Mussolini wanted the station to represent the might of Italy's Fascist regime, so the architecture and details were tweeked to represent what's now called "fascist architecture". The architectural details are powerful but not very refined, and are present throughout the structure.
Although we used the station twice, I never managed to head outside (given the luggage we were totting), so I didn't photograph the exterior. However, here is a nice photo of the entrance, courtesy Wikimedia and Daniel Case.
