Light Obelisk

It was the first glass obelisk in the world and was designed in 1987 by Prof. Heinz Mack. It wasn't just its materials that made the 35m high tower unique, but also the many  electronic tricks, which controlled the appearance of the obelisk. This meant the appearance of the 35m high tower could be changed depending on location, time of day and light intensity. The obelisk was created by Prof. Heinz Mack as an expression of artistic freedom, but also stood as a symbol for freedom in Berlin.The light obelisk is situated next to the Tauentzienstraße entrance.
