Guided Tour of Fjordenhus

Vejle Art Museum's own guide walks you through parts of Olafur Eliasson's Fjordenhus — a nice way to actually understand the architecture rather than just walking past it. It's an indoor tour, all ages are welcome, and English-language tours are available so you won't be lost. Check the museum's site for times and pricing, and I'd grab a spot a bit ahead since guided groups can fill up.
