Nordiska Museet, which explores Sweden's cultural heritage, was founded by Artur Hazelius, the man behind zoo/museum Skansen just down the road. The collections are comprised of a hefty 1.5 million objects, dating from the 16th century and onwards. Everyday objects, elements of clothing and fashion, letters, diaries, 250,000 other books and journals, and seven million photographs can all be found here. It sounds a little dusty—there are no interactive displays or computer monitors— but the 10–20 annual exhibits are curated to suit a contemporary audience and offer low-falutin' themes such as "Small Stuff," "The Bathroom," "Old People," and "The Guillotine" (Sweden's only). It's all housed in a magnificent 1907 building with an elaborate Dutch-influenced Danish-Renaissance design and a glorious, cathedral-like main hall. The museum only attracts a fifth the number of visitors of its smaller neighbor Vasa, but that's part of the point. Block out at least 2 hours to do it justice, and a full afternoon to really get under Sweden's skin.
