Photographer's comments: 

The Reichstag building in Berlin was constructed to house the Reichstag, parliament of the German Empire. It was opened in 1894 and housed the Reichstag until 1933, when it was severely damaged in a fire supposedly set by Dutch communist Marinus van der Lubbe.

Rebuilt after it was mearly destroyed during World War 2, The Reichstag building now features a glass dome. The Reichstag dome is the large glass dome at the very top of the building.

The dome has a 360-degree view of the surrounding Berlin cityscape. The main hall of the parliament below can also be seen from the cupola, and natural light from above radiates down to the parliament floor.

A large sun shield tracks the movement of the sun electronically and blocks direct sunlight which might bedazzle those below.
