There is a place in Iceland that houses different types of male genitalia particularly that of animals and reportedly of trolls. The Icelandic Phallological Museum is known to hold the largest display of penises and penile parts.

The Icelandic Phallological Museum is located in Reykjavík, Iceland. The museum houses the collection of 280 specimens from 93 species of animals includes 55 penises taken from whales, 36 from seals and 118 from land mammals. Reportedly the Icelandic Phallological Museum also house those of Huldufólk (Icelandic elves) and trolls.

The Icelandic Phallological Museum was founded in 1997 by a retired teacher Sigurður Hjartarson. Now run by his son Hjörtur Gísli Sigurðsson, the Icelandic Phallological Museum grew out of an interest in penises that began during Sigurður's childhood when he was given a cattle whip made from a bull's penis. Smithsonian Mag notes that the museum claims that its collection consists the penises of elves and trolls, though, as Icelandic folklore portrays such creatures as being invisible. The collection also features phallic art and crafts such as lampshades made from the scrotums of bulls.

The Icelandic Phallological Museum has become a popular tourist attraction with thousands of visitors a year and has received international media attention, including a Canadian documentary film called The Final Member, which covers the museum's quest to obtain a human penis. According to its mission statement, the museum aims to enable "individuals to undertake serious study into the field of phallology in an organized, scientific fashion.

In July 2011, the museum acquired its first human penis from one of its donors. However, its removal from the donor's body did not go as planned. The organ was reduced to a greyish-brown shriveled mass that was preserved in a jar of formalin. The Icelandic Phallological Museum at present continues to search for a younger and a bigger and better one.
