I visited Berlin before Christmas in 2011, 2012 and here in 2014. On this occasion we got tickets to visit the dome at the top of the Reichstag (Federal Parliament). Our slot was in the late afternoon / early evening and without a tripod, I had to make do with handheld high ISO shots and a very steady hand!
All within easy walking distance of each other, the Reichstag (parliament), the Brandenburg Gate – both fully restored after substantial damage during the Second World War and the Holocaust memorial, built some way to the south of the Brandenburg Gate, are popular tourist spots in Berlin. Further away, at the Alexanderplatz is the Weltzeituhr (World Time Clock), showing the time in major cities around the world.
