Continuing our journey along Germany’s “Walk of Ideas” we arrive at a giant pill entitled “Milestones of Medicine”. Then there’s “Milestones in Music” – a collection of giant musical notes in front of the Konzerthaus. Which leads us to “Modern Book Printing” – a large pile of books by Schiller, Lessing, Fontane, etc. And last but not least, “The Theory of Relativity“, a giant E=MC2. Which, uh, seems to have gone missing! Ah well, there’s pictures and descriptions of all 6 sculptures on the official website. Thanks: Me, Myself & I.
