Located across the Reichstag's building in Tiergarten, the recently completed Kanzleramt was opened in 2001. Architect Axel Schultes designed the 9-story building, where the German Chancellor has his/her office and residence (although none of the Chancellors have decided to live there until now). The access to the building is currently restricted so, unlike the Reichstag, visitors cannot enter it. Made of concrete and huge glass panels, it's an impressive edifice that symbolizes the reunification between East and West Berlin.
