Much of the city’s magic is often a bit of the visual field we usually use when we rush through the city streets. We passed the brick building without reflecting noteworthy that the façade of Oslo Spektrum is actually a huge and very beautiful artwork. When architects LPO planned the building, they hired artist Guttorm Guttormsgaard to do the exterior decoration. In collaboration with ceramicist Søren Ubisch, and old print fragments of late artist Rolf Nesch, the building has become a gigantic artwork, consisting of over 400. 000 bricks.
