This guide is aimed at those who like to explore, take photos, learn a little about their surroundings, & for visitors who want to see places not on the tourist trail.
This is about the real city & some of that might be dirty; it might sound disparaging in parts; it might make you wonder what the hell kind of awful person would write a guide to the 'dirtiest bits of the canals', but be assured this is all because I love the city & encourage you to explore beyond the shopping districts & bars - maybe then some of those areas will improve, in time.
Maybe not.
But along the way you'll see things that might interest you - an old gas lamp post, an old fire alarm bell, a plug socket on a bridge. If, that is, you find weird useless crap interesting.
