The Gherkin is one of London's most famous skyscrapers. The reason for the name is simply that it is shaped like a Gherkin. The conical shape and patterned harlequin-patterned glass makes it the most iconic building in London. Built by Norman Foster, this innovative building is supposedly the first environmentally sustainable skyscraper. It contains offices and a restaurant which is the highest restaurant in London. This building is aesthetically pleasing and also great to spot.
