Did you know that? Trolls are an important part of Norwegian folklore. They vary in size and appearance, but are invariably ugly and messy creatures, and always mischievous (if not downright nasty). They usually live in caves or deep in the forest, and only emerge from their hiding places after sunset - legend has it that they turn to stone upon contact with the sun. Several places in Western and Northern Norway have been named after them, such as Trollheimen, Trollstigen, Trollhatten and Trollveggen.
