Opened to much controversy in 2013, Ekebergparken cemented Oslo's reputation as a contemporary-art capital and, in particular, one devoted to sculpture. This vast forested public park overlooking the city and the Oslofjord is dotted with work from the collection of property developer and art collector Christian Ringnes, with artists represented including Louise Bourgeois, Marina Abramović, Jenny Holzer, Tony Oursler, Sarah Lucas, Tony Cragg, and Jake and Dinos Chapman, plus a few traditional works by Auguste Rodin, Aristide Maillol and Gustav Vigeland.
You'll need at least half a day to explore properly, and expect your visit to unfold more as a treasure hunt than a usual museum experience. While seeking out the various installations, make sure you visit the Ekeberg Steps, a historic as well as breathtaking viewpoint, and the Munch Spot, with a view that inspired The Scream (as well as a 2013 Abramović work). Children's activities are held in the Swiss-chalet-style Lunds Hus, where you'll also find the Ekebergparken Museum, which has displays exploring the geological and natural world of the park, as well as an art and design shop.
