Cologne is also checked on my travel list now! I stayed only one night, but I saw quite a couple of things and I even climbed the Dom, which I didn’t think I would every try in my life (remember I am terribly afraid of heights!). I have a few friends here, so it will be easy to come back again, if I ever feel the need of risking my life and climbing 4000 steps, just to have a good overview and maybe a nice capture.
