When I travelled to Bonn for a few days I could manage to visit Cologne only once, for half a day. But I cherished every moment of it that I spent visiting the Cologne Cathedral and a walk by the Rhine river. And this was spiced up by an occassional chat with a citizen who always shared some story about the city.
The railway bridge in Cologne has a very interesting sight. All along the walkway you can see the railings lined up with thousands of keypads. I was informed that these locks are tied by couples who want to stay bonded for life. No one knows when and how this tradition developed but the delightful sight of the lockpads never fails to attract passersby.
As night descended I headed back to Bonn. And just before I boarded the train back to Bonn I did not forget to pick up a small bottle of the famous 'Cologne' fragrance.
