Day 1 — Arrival in the Ruhr: Essen, the old center and the “meeting point”
✈️ Arrival at Düsseldorf Airport (DUS) or Köln/Bonn (CGN) → train to Essen Hbf. Check-in and an easy walk: Burgplatz with Essen Cathedral (Essener Dom) and the line of the old abbey, where you can already feel the link “early Middle Ages → industrial era.” The square makes the city’s scale easy to read: from cobbled frontages to modern inserts of glass and steel.
🌆 In the evening — viewpoints from Kettwiger Straße to the Domschatz (treasury): the “jewel-box” building next to the cathedral hints that the route ahead will be about things “in the hand” and “in stone” — relics, slabs, fragments of masonry.
