Underpass at Berlin Hauptbahnhof with Spree River

Beneath the elevated tracks of Berlin Hauptbahnhof, Germany's central railway station, a pedestrian path runs alongside the Spree River. The station, a major transportation hub opened in 2006, was designed to symbolize a reunified Berlin and connect the city's north-south and east-west rail lines. Its modern glass and steel architecture stands in contrast to the utilitarian underpass, which is bordered by temporary fencing and overgrown vegetation. This perspective highlights the functional infrastructure supporting one of Europe's busiest transit centers.
