A skyscraper in London's main financial district, which has become a very distinctive landmark on the skyline. It is informally known as "The Gherkin", but officially as The Swiss Re Tower, or just Swiss Re, after its principal occupier. It is 180 metres tall, making it the 2nd tallest building in the City of London, and the 6th tallest in London as a whole. The radical (and somewhat phallic) design is by Sir Norman Foster and ex-partner Ken Shuttleworth, and the building was constructed between 2001 and 2004.
"What's that giant glass penis doing in the middle of London?"
"Oh, that's just the Gherkin built by Norman Foster."
