Graffiti fan? As well as the bird at Strip-S, the skeleton at Studio Driftig in the Nieuwe Emmasingel, you really should go to the Berenkuil, a roundabout with plenty of space in the middle for graffiti. The entire roundabout is given a fresh layer of paint during the annual 'Step In The Arena'.
Section-C has a lovely mural with a bird. It’s a bit further out from the centre, so stop by for something to eat while you’re there.
