World Time Clock, Berlin — Visitor Guide & Things to Do Nearby
About World Time Clock
The World Time Clock (Weltzeituhr) is one of Berlin's most recognizable landmarks, a 10-metre-tall rotating metal structure on Alexanderplatz that shows the time in all 24 time zones simultaneously.
The clock was designed by Erich John and unveiled on September 30, 1969, two days before the 20th anniversary of the German Democratic Republic. It was part of a major redesign of Alexanderplatz by the East German government, intended to showcase socialist modernity.
The structure consists of a rotating aluminium cylinder displaying the names of 148 cities arranged by time zone. Above the cylinder sits a simplified model of the solar system, with the planets orbiting a central sphere. The entire upper section rotates once per hour.
Despite being a product of the GDR, the World Time Clock survived reunification and has become one of the most popular meeting points in Berlin. It was restored in 1997 and again in 2015, with city names updated to reflect geopolitical changes since 1969.
The clock stands in the centre of Alexanderplatz, surrounded by the Fernsehturm (TV Tower), the Marienkirche, and the Galeria Kaufhof department store. It is one of the most photographed objects in Berlin and a symbol of the city's complex history.
If you're on a Questo quest through Alexanderplatz, the World Time Clock is a stop where Cold War design, global time, and Berlin's talent for reinvention all revolve around the same axis.
