Surely the world’s only museum to showcase the phalluses of an entire nation’s mammalian wildlife, Iceland’s Phallological Museum is somewhat unique. Despite its obvious quirk factor, the museum is actually an interesting and—for the most part—fairly serious establishment. It offers guests the chance to inspect almost 300 penises (including parts of penises) that together represent pretty much all the land and sea mammals to be found throughout the country. A quarter belong to various types of whales, but there are also samples from polar bears and seals, as well as a letter from a local human pledging his own personal specimen posthumously. There are also elf penises, though you’ll need special psychic powers to see them.
