Started with a little detour to the Clara Zetkin memorial – Clara-Zetkin-Gedenkstätte – which is a small museum with a library and a sculpture garden. I did not go in, but I think it is open to the public now.

The sculpture boulevard in Birkenwerder:

Bonus tip: There are NO PUBLIC TOILETS in Birkenwerder, and also not really any cafés to stop at, so on the way home I got off at the next station (in the direction of Berlin) where there is a public toilet on the square in front of the station. Also this sculpture:

And almost home, I could not resist getting off the train at S-Bahnhof Pankow-Heinersdorf to take a few photos of the former Güterbahnhof Pankow, soon to be demolished (it seems to be doing a pretty good job at doing that all by itself).
