Opened in 1926, the Zeiss Planetarium is the oldest planetarium in the world and also the biggest in Germany thanks to its 25-metre dome.
Its repertoire includes astronomy and general education programmes for adults and children, musical shows, children's events and spectacular multimedia laser shows. A laser all-dome projection system was installed in October 2006. The Zeiss Planetarium is now one of only two planetariums in the world offering shows with images that cover the entire dome.
