Berlin to the Rhine (S01E03)

Michael begins this journey in Berlin, the capital of Germany, which at the beginning of the 20th century was a powerhouse of science and technology. Led by his 1913 railway guide, he then heads west via the picturesque Harz Mountains to the industrial Ruhr Valley to learn how imperial Germany was war ready. He then travels south along the tourist trail of the castle-studded Rhein river and ends his journey in the Rheingau to taste the wines of its age-old vineyards. (BBC)
