I was very much in a "black and white" mood and took the following photos whilst there.
Later that evening we were to entertain two friends from the Unitarischen Kirche in Berlin and perhaps that is why as I walked I had Proverbs 4:23 in my mind, the text that was written above Heidegger's front door in Freiberg:
Behüte dein Herz mit allem Fleiß; denn daraus geht das Leben (Luther).
Keep thy heart with all diligence; for out of it are the issues of life (KJV).
Keep your heart with all vigilance, for from it flow the springs of life (NRSV).
