The World Clock (German: Weltzeituhr; German pronunciation: [ˈvɛltt͡saɪ̯tˌʔuːɐ̯] ), also known as the Urania World Clock (German: Urania-Weltzeituhr), is a large turret-style world clock located in the public square of Alexanderplatz in Mitte, Berlin. By reading the markings on its metal rotunda, the current time for 148 major cities from around the world can be determined.[1] Since its erection by the German Democratic Republic in 1969, it has been a tourist attraction and meeting place. In July 2015, the united German government declared the clock as a historically and culturally significant monument.[2]
