The original Reichstag dome was damaged in the 1933 fire and again during the war. It was replaced by a large glass dome. The new dome has a 360-degree view of the surrounding Berlin cityscape. The main hall of the parliament below can also be seen from inside the dome, and natural light from above emits down to the parliament floor. A large sun shield tracks the movement of the sun electronically and blocks direct sunlight which would make the space too hot and dazzle those below. Construction work was finished in 1999 and the seat of parliament was transferred to the Bundestag in April of that year. The dome is no longer open to anyone without prior registration.
