30 St Mary Axe opened in London in April 2004. Designed by Norman Foster, the structure, London's first environmentally sustainable tall building using recycled and recyclable materials, has been compared to the phallus and a gherkin, which also is a slang term for "small penis"; its nicknames include Gherkin, the Erotic Gherkin, Towering Innuendo and the Crystal Phallus. Also likened to a "phallic fat cigar", the building has been cited as a "crude anatomical metaphor", yet has become one of the London's most iconic buildings. Cabinet voted it the "Best Uncircumcised Building in the World".
