Although technically street art is illegal, it has become an art form in itself, to the point that some people are now decorating their own buildings/homes intentionally in this urban art style. The building above is an example of this, I believe. It’s along the northern part of the Oudegracht, outside the city center, just north of the Weerdsluis. I’m pretty sure this building was decorated like this by choice, otherwise, there must have been an impressively large, speedy group doing this!
Of course, not all street art is commissioned, but that doesn’t stop some of it from being truly fantastic. While Banksy is probably the best known street artist these days, there are plenty of people doing thought-provoking and visually interesting pieces. AVRO, a Dutch public broadcasting group that puts a lot of focus on art and culture, is putting together a map of some of the great street art of the Netherlands. So far, only one piece from Utrecht seems to be on the list. Hopefully more will be added, though. I suppose I should send them some photos!
