A wonder cabinet of wonder cabinets, the Museum Gustavianum rewards appreciation of the weird and well organised. The shelves in the pleasantly musty building hold case after case of obsolete tools and preserved oddities: stuffed birds, astrolabes, alligator mummies, exotic stones and dried sea creatures. A highlight is the fascinating 17th-century Augsburg Art Cabinet and its 1000 ingenious trinkets. Don’t miss Olof Rudbeck’s vertiginous anatomical theatre, where executed criminals were dissected. Admission includes a tour in English at 1pm Saturday and Sunday.
