A myth has been brought back to life. Potsdamer Platz, the epitome of urban life in Berlin before the war, was reanimated after 1989. The Potsdamer Bahnhof — the cradle of Berliners’ railway network in 1838 — was also redeveloped: no longer the terminus of the trains from the south, but an underground stop of a four-track rail tunnel in north-south direction, which runs under the debis and Sony high-rises, is tangent to the S-Bahn, and still finds room to widen into a 50-metre-wide, 260-metre-long, and 15-metre-high, underground hall. As a spatial continuum, it extends from the four tracks with the platforms in the depths to the Passarelle, a wide walkway along the outer walls, to the large hall under the wide exits to the square.

Practical constraint becomes form: the enormous mushroom supports on which the Renzo Piano high-rise rests, the stepped trough in which the future U-5 crosses the hall under the ceiling. A lightless and windowless room becomes a luminous cave, a druse. Backlit glass walls, light-reflecting terrazzo floors, a thin steel mesh under the ceiling — through which fine spot beams penetrate — create shimmering surfaces that obscure the heaviness of the adjacent masses. The sense of dislocation so often caused by underground spaces turns into lightness.

On the square, two steel pavilions mark the main entrances, corresponding to a vestibule. They are aligned with the grid of Friedrichstadt and Potsdamer Platz.
