Liège-Guillemins Railway Station
Spanish architect Santiago Calatrava designed the latest incarnation of the Liège, Belgiumis rail station using steel, glass, and white concrete. His version, completed in 2009, replaces a 1958 International Style building (which itself replaced an 1842 Beaux Arts structure), intentionally lacks a single façade in order to unite two neighbourhoods previously separated by the railroad tracks.
