Designed by Renzo Piano, this private contemporary art museum is housed in a wonderful building of silvered wood, with a sail-like glass roof that feels both maritime and at one with the Oslofjord landscape. While the museum's original collecting brief was conceptual American work from the '80s (with artists of the ilk of Jeff Koons, Tom Sachs, Cindy Sherman and Richard Prince well represented), it has in recent times broadened beyond that, with, for example, a room dedicated to Sigmar Polke and Anselm Kiefer.
Its most famous piece remains, however, the gilded ceramic sculpture Michael Jackson and Bubbles, by Koons, and there are also large works by Damien Hirst. The temporary shows range from the monographic, say Matthew Barney or young Norwegian artist Matias Faldbakken, to thematically tight curated surveys such as New Norwegian Abstraction or Chinese conceptual work. There are tours at 2pm each Sunday (50kr).
