It was very late when I arrived in Budapest, but a consolation to be in a hotel close to the Danube. To me, there is something sacred about rivers. I dropped my bags in my room and went there straight away to gaze upon the same flow that was once viewed by Attila the Hun, St Stephen of Hungary and Raoul Wallenberg. In the darkness, the reflections of promenade lamps shimmered gold upon the surface of Europe’s second longest river as it stretched lazily through the capital, as broad and as beautiful as the Thames in London and presenting the same metaphorical passage of time.
