The Icelandic Phallological Museum (Icelandic: Hið Íslenzka Reðasafn), located in Reykjavík, Iceland, houses the world's largest display of penises and penile parts. The collection of 280 specimens from 93 species of animals includes 55 penises taken from whales, 36 from seals and 118 from land mammals, allegedly including Huldufólk (Icelandic elves) and trolls. In July 2011, the museum obtained its first human penis, one of four promised by would-be donors. Its detachment from the donor's body did not go according to plan and it was reduced to a greyish-brown shrivelled mass pickled in a jar of formalin.
