30 St. Mary Axe in the City of London.
30 St. Mary Axe, widely known as the Gherkin and also the Swiss Re, is a neo-futuristic skyscraper in London's financial district. Opened in April 2004, the building stands at forty-one storeys and was designed by famed high-tech architect Norman Foster and the Arup Group. Although the building was criticized initially, it has become an iconic symbol of London. The glass dome at the very top of the building—which has a lovely little bar along with 360 degree views of London—can be hired out for business functions and weddings. Next office party?
