After a few years in Singapore, you get used to everything being clean and neat and tidy. Which is good as a living environment, it is safe and predictable. But that can also get a bit boring in some ways. So occasionally it is nice to visit a little chaos, especially controlled chaos like Barcelona where you feel safe but there is the added interest of the street art / graffiti you can see spotted around the Gothic quarter of Barcelona – Barrio Gotico, right in the centre of the old town. I took a few pictures of what I saw but there is loads more for you to explore if you go to Barcelona (which you should if you haven't been!) I especially liked the Hitler with an afro.
