Daniel Libeskind designed this museum in a wing of the Royal Library, and his sloping walls and glass can feel as disorienting as a fun house, but that's it's greatest distinction. A critical problem with this museum is that the story of the Jews in Denmark has never been unified—there were never very many, and the museum admits that the Jews who did live here didn't get along; they argued so long about how to rebuild a synygogue that for decades, nothing got constructed. Therefore, many of the cases are actually devoted to instructing visitors about the general ways of Judaism. That might be fine for a Dane who doesn't know many Jews but if you're already familiar with the relgion, it won't present more than some mildly interesting old artifacts, and that's not worth the price.
The real story that most outsiders want to learn about the Jews in Denmark—the way so many of them were miraculously protected from the Nazis through special laws and then ushered to safety in Sweden—is only given two paltry display windows that don't go into much depth. Frequent themed exhibitions, usually artistic in nature, pep up the offerings, so see what's on, but for the most part, this museum doesn't tell you the stories you most want to know.
