The glass-and-concrete Paul-Löbe-Haus houses offices for the Bundestag’s parliamentary committees. It's filled with modern art that can be viewed during guided tours (in German) at 2pm on Saturday and Sunday. Advance online registration (www.bundestag.de) is required.
From above, the imposing building looks like a double-sided comb, while the central atrium on the inside could double as a bowling alley for giants. A double footbridge links it to the Marie-Elisabeth-Lüders-Haus across the Spree in a visual symbol of reunification.
