weltzeituhr

On this day in 1969, to commemorate the upcoming twentieth anniversary of the founding of the DDR, the iconic structure also known as the Urania World Clock (for the Uraniasäule that was destroyed in the war which it replaced as a public timepiece) was unveiled to the public in East Berlin’s Alexanderplatz as part of a plan to modernise the square and make it a showcase for the world. Envisioned by Czechoslovakian designer Erich John, the metal rotunda supported by a twenty-four-sided column representing the main time zones of the Earth displays the current time for one hundred forty eight cities, periodically updated to reflect contemporary geopolitics. The turret mechanism is in constant motion but it is imperceptible except in time-lapse.
