Beco do Batman

What makes it different and cannot be seen from above is that every single wall in its 100m extension is covered top-to-bottom with graffiti of all shapes and colours.

The graffiti here are not the average large-letter tags, although there is a lot of that.

Batman's Alley or Beco do Batman, in Portuguese, resembles more an open-air street art gallery, where abstract, surreal, psychedelic and geometric paintings colourfully co-exist.
