This entire area in full of street art and graffiti - all on legal walls.
Currently, this wall is painted by Manoel Quitério (the artwork on the photos) (December 5th, 2018).
This is the wall of the venue Radar.

To get a better idea of this area and its vibes, take a stroll in the area - it is never boring and there is much more street art than is shown here on Street Art Cities. You can also look at http://grandts.dk/Aarhus/godsbanen.htm
