Last time we were in Berlin during the winter was in 2007-2008, and we enjoyed it a lot. We have wanted to go back during the cold season again, because Berlin is an all-year-round city. This year we visited among other places the Gemäldegalerie and the Neue Nationalgalerie (old and new art). I also visited a concert at the Charlottenburg Castle in the evening of the 7 January 2011. They played Vivaldi and Bach, which was delightful to hear live.
