Watch: World's largest museum for an artist? Munch gets new home in Oslo

To Edvard Munch, they were his children. And like any doting father, he hated the idea of them straying too far from home.

Now, more than 26,000 artworks from the master expressionist's "family" - including his best known piece, The Scream - have moved under one roof in the enormous and custom-built MUNCH museum on the shore of Oslo Fjord.
