Mirrored cone inside the Reichstag Dome, in the german parlament (Reichstag), Berlin. The current Reichstag dome is an iconic glass dome constructed on top of the rebuilt Reichstag building in Berlin. It was designed by architect Norman Foster and built to symbolize the reunification of Germany. The distinctive appearance of the dome has made it a prominent landmark in Berlin. 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 dome is open to the public and can be reached by climbing two steel, spiraling ramps that are reminiscent of a double-helix. The glass dome was also designed by 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. The futuristic 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.
