Rockheim Trondheim

This terrific museum is devoted to pop and rock music, mainly Norwegian, from the 1950s until yesterday. It's a dockside temple to R&B, where a huge projecting roof featuring Norwegian record covers extends above an equally vast converted warehouse. Within, there's plenty of action and interaction (mix your own hip-hop tape, for example). Home of Rock is on the quayside, very near Pirbadet and the fast-ferry landing stage. From mid-June to mid-August, there's a free, English-language guided tour of the museum.
