Berlin's Reichstag, home to German Bundestag (Parliament). Take a stroll on the rooftop with this spherical panorama. The glass dome is cool, you get a 360 degree view of Berlin, and the whole thing is apparently rather environmentally friendly. Very German. Very Berlin.
If you look more closely, you'll also see cranes in the distance — a skyline feature of Berlin's continual redefinition. Even though it has been 20 years since reunification, the city is still constantly changing, evolving.
360-Degree Panorama: Reichstag Rooftop and Glass Dome – Berlin, Germany
Unfortunately, gone are the days when you could just show up on the steps of the Reichstag and head up to the roof to poke around and enjoy the view. These days, the visit is still free, you'll need to book your visit in advance. Check out the Bundestag website for more information.
