Traffic control, '50s style
In Berlin's post-war years the devastated city required extensive rebuilding, and visions of a futuristic new metropolis abounded.
In the West, shopping malls and angular apartment blocks rose alongside salvaged remnants of the past. In the East, concrete towers began to dominate the skyline.
It was predicted, too, that with the introduction of new traffic-light systems, levels of peak-time congestion would reach unmanageable proportions. In order to help solve the anticipated problem, a traffic control booth was constructed in 1955 above the revamped entrance to Kurfürstendamm's U-Bahn station.
Various others were erected around the city: none were ever really needed.
This so-called Verkehrskanzel was last used in 1962, and remains as a curious, scarcely noticed reminder of a future-proofing precaution that never came to pass.
