The Glienicke Bridge across the Havel River connects Berlin with Potsdam.
During the Cold War, and until the fall of the Berlin Wall, the bridge was a point for exchange of imprisoned secret agents.
It became known as the Bridge of Spies, and features in a Steven Spielberg movie of that name released in 2015.
A frisson of excitement went through our tour group on the bus as we crossed this historic place, and went on to see Potsdam, formerly the jewel of the Prussian Empire and the home of Kings and Kaisers, their most famous palaces and their vast armies.
We went to Sans Souci, the former summer palace of Friedrich the Great (1712-1786) and, following the reunification of Germany in 1990, his final resting place.
More like a large single story chateau, this dainty Rococo style palace has just ten principal rooms, all styled in Friedrich's personal taste now characterised as 'Frederician Rococo'.
As I lover of pink, I was entranced by its sugar-candy sweetness and style...
After a walking tour of the historic centre of Potsdam we enjoyed the contrast of a visit to the Museum Barberini, Potsdam's very new fine arts gallery, where I enjoyed some fine Kandinskys:
At evening we embarked on the Elbe Princesse, our floating hotel for the next week...
Drifting into the sunset along the Havel River towards the Elbe..
and on into the night.
We had the river to ourselves, and never saw another cruise boat.
