The Icelandic Phallological Museum, located in Reykjavík, Iceland, is home to the world's largest collection of penises and penile parts. Founded by retired teacher Sigurður Hjartarson in 1997, the museum boasts over 300 penises from more than 100 species of mammals, including mythical creatures like elves and trolls. Visitors can marvel at specimens ranging from a massive blue whale penis to the tiniest hamster baculum. The museum has gained international attention and even features a cast of a man with "the longest urinary measurement ever recorded." It's definitely a unique and quirky tourist attraction that aims to promote the study of phallology in a fun and organized way.
