Wiki: The Reichstag dome is a large glass dome with a 360 degree view of the surrounding Berlin cityscape. The debating chamber of the Bundestag, the German parliament, can be seen down below. A mirrored cone in the center of the dome directs sunlight into the building. The domecan be reached by climbing one of two steel spiraling ramps (one up and another down) that are reminiscent of a double-helix.
The glass dome was designed by Norman Foster to be environmentally friendly. Energy efficient features involving the use of the daylight shining through the mirrored cone were applied, effectively decreasing the carbon emissions of the building. [3]
The futuristic and transparent design of the Reichstag dome makes it a unique landmark, and symbolizes Berlin's attempt to move away from a past of Nazism and Communism and instead towards a future with a heavier emphasis on a united, democratic Germany.
