The History of Alexanderplatz

Alexanderplatz, often referred to simply as “Alex,” has been a central square in Berlin since the Middle Ages. It was initially named after the Russian Emperor Alexander I when the city was under Russian occupation during the early 19th century. Over the years, Alexanderplatz has witnessed significant historical events, including political demonstrations, protests, and even major urban reconstructions.

The World Clock

At the heart of Alexanderplatz stands the World Clock, a renowned landmark that has been an integral part of the square since the 1960s. The clock was designed and built by Erich John, Günter Hammerschmidt, and a team of skilled craftsmen.

The World Clock is not just an ordinary timepiece. It consists of a rotating cylindrical structure with multiple clock faces, each displaying the time in a different city around the world. The cities represent different international time zones, allowing visitors to see the current time simultaneously in various global locations. It’s a convenient feature for travelers or those who want to keep track of time around the world.

The cylindrical structure of the World Clock is over ten meters high and weighs approximately sixteen tons. It features an impressive combination of functionality and aesthetics, making it truly captivating. The clock displays the time in 148 cities across all continents, including major capitals and metropolises.

Each clock face is meticulously designed with precision to ensure accurate timekeeping. The cities are marked on the clock’s cylindrical surface alongside their respective time zones, making it easy for visitors to identify different locations and their local times.

Additionally, the World Clock is equipped with a light display that illuminates different sections of the globe depending on the time of day. This dynamic feature adds a visual element to the experience, allowing observers to see the changing patterns of daylight around the world.

The Significance of the World Clock

The World Clock on Alexanderplatz is not only a practical timekeeping device but also an important symbol of Berlin’s history and resilience. It represents the city’s past division and subsequent reunification as well as its global connections.

During the Cold War, Alexanderplatz was part of East Berlin, just a stone’s throw away from the Berlin Wall. The World Clock served as a reminder of the divide between East and West and the contrasting ideologies of the era.
