Liège-Guillemins railway station is the main station of the city of Liège, the third largest city in Belgium. It is one of the most important hubs in the country and is one of the three Belgian stations on the high-speed rail network.

Calatrava conceived the station as a link between two distinct areas of the city of Liège, which was separated previously by the railroad tracks. North of the site is a rundown urban area, laid out in a typical 19th century style. The slopes of the Cointe Hill located on the south host a less dense, landscaped residential area. Calatrava designed a 200-meter-wide passenger terminal, built symmetrically about a northwest-southeast axis that bridges these two distinct areas with an arched roof for the terminal building, which extends over the five train platforms for a further 145 meters.

The project has no facade in the traditional sense, since the interaction between interior and exterior is seamless. The monumental roof becomes, in effect, the project’s facade. To an observer on the hill, the roof reveals something of the inner organization of the station. To an observer within the station, the arches frame provides commanding views to the outside. From any vantage point, the sensation of transparency prevails.
