One afternoon for Berlin

I had one afternoon to explore Berlin, We raced around the city exploring all the top sights like the Reichstag, and Brandenburg Gate. We took Europe's fastest elevator up Panoramaounkt in Potsdamer square. I played the absolute tourist and was totally taken in my the beautiful lights in Potsdamer Place as it grew dark.
Even though the architecture is incredibly dominating and defensive and unfriendly, I just love the chunky shapes, especially from above looking at the flat rooftops and jigsaw of grouped buildings.
