As quite a few of the Invisible Cities that I've done thumbnails for, so far, include water or Seas and Oceans etc. I thought I'd look at existing cities where water is either running through them or beside them. Some cities, like Venice, has the Grand Canal running right through it, so it plays a major role in the city layout and how people get to places. But other cities, like London, have big rivers, in this case River Thames that doesn't play that big of a part in the City layout. As I mentioned in the last Influence Map post, I really like Italy, so because of this I will look into Venice and similar Italian cities in more detail.
