Lyon is hills. By which I mean, two of the main areas of Lyon are built on hills: the vieux Lyon area with the Notre Dame de Fourviere Cathedral, and the centre Lyon area which is made up of Croix-Rousse (red cross + hospitals) and old, cobblestone, pedestrian only areas. I trapezed up to these two areas one day; read- I climbed a lot of stairs. But every now and then I looked back, and this is what I saw. Amazing.
