30 St Mary Axe, otherwise known as "The Gherkin" or the Swiss Re building, at 180 m (590 ft) is the 6th tallest in London, England. Designed by Foster and Partners, the architectural design of the tower contrasts sharply against more traditional buildings in London. Its design won the prestigious RIBA Stirling Prize for the best new building by a RIBA architect in 2004 and the 2003 Emporis Skyscraper Award for the best skyscraper in the world completed that year. The building is visible from a long distance from Central London: from the north for instance, it can be seen on the M11 motorway some 32 km (20 mi) away.Photo credit: Diliff
