das Reichstag. seat of the German parliament, the new dome by Foster+Partners serves as a light collector funneling natural light into the central chamber of the parliament as well as a viewing platform for the public to see within the chamber from above. the dome expresses the public accountability and transparency of the parliament connecting the people with the state. the detailing is as immaculate as the clarity of the translation of the design concept into built form. in these terms, one of the most successful projects i have had the chance to experience thus far.
