Our usual express train to Potsdam not running, we improvised and took a suburban trip to Potsdam and then a long bus ride through Potsdam itself before emerging on the edge of Frederick the Great’s sprawling complex of palaces. Starting by the massive Neues Palais, we wandered down the central spine of the extensive grounds, forests on either side, with baroque follies, elaborate gazebos, and even windmills peeping out or towering over the dense trees. Reaching the central nexus of fountains, we climbed the carefully manicured grounds to Sans Souci, Frederick’s relatively snug palace. A tour of its dozen or so open rooms induced rococo overdoses: decoration piled on decoration, all gilded or filigreed or fussed over. A bus took us back to the Potsdam Hauptbahnhof for a quick lunch before an 18-stop, 3-line subway ride returned us to our hostel for a couple of hours’ rest and homework (one can hope, right?) before the group was given free rein of our Kreuzberg neighborhood for dinner on their own. Tomorrow, our last full day in Berlin, will include a little of everything: Egyptian art, World War II History and shopping.
