Düsseldorf is a city with two faces two hundred metres apart. The Rhine promenade is plane trees, steps down to the water and, on a summer evening, full of people; the Medienhafen behind it is Gehry, glass-clad slopes and after office hours effectively empty. One gives warm soft light and movement, the other hard edges and reflection — and because they are joined on foot, this is the rare session that gets two entirely different registers without anyone getting into a car.
The old town between them is a harder subject than it looks: the lanes are narrow, after seven in the evening it is a drinking strip, and in the morning it is being delivered to. If you want it, go early on a Sunday. What Düsseldorf also has and almost nobody plans for is the Japanese quarter around Immermannstraße — the third-largest Japanese community in Europe, with signage, shops and a visual language that exists nowhere else in Germany.
