Gherkin is the informal nickname given to 30 St. Mary Axe, standing prominently and reaching out for the skyline in the historic region of London. It is one of the modern buildings of London’s historical area which, for its construction got commissioned by a reinsurance company named Swiss Re. The previous name of the 41 storey skyscraper, Swiss Re building was eventually changed to 30 St. Mary Axe with regards to its address. The building, subsequently adopted the name ‘Gherkin’ for its distinct shape. The hi-tech building in London’s financial centre lies on a comparatively low rise area surrounded with an array of historical buildings and narrow medieval streets.
It resembles the cigar and consists of circular floor plans and a glass facade. The exteriors have been developed with an energy saving system, where the air is to flow up through the spiraling wells. The base of the building has a public plaza and while entering, the top of the tower, covered with glass conical dome enhances the entire outlook. But, entering the building is prohibited for the common masses. Stirling Prize, the London Region Award, and the Emporis Skyscraper Award etc are the rewards received by the building for its unique and startling design.
