I haven’t been there in seven years now and Berlin seems to change pretty rapidly, but I will try to offer up a few things. If you like a view, check the Fernsehturm. Unter den Linden is beautiful, and I found the Holocaust memorial to be very powerful.

I found the former East Berlin to be more interesting, with things like an art collective that basically took over an abandoned building. I am sure that isn’t there anymore though.

Check out the Berlin Wall Memorial including a preserved section of no man’s land.

Have a doner kebab on the street, and relax with a beer (even though they are much better in Bavaria!). Have fun!
