The building has got the nickname since It looks like a gherkin. This building was designed by an English master architect, Norman Foster. His famous works are, Hong Kong International Airport、HSBC Headquarter building. Recently he designed a viaduct in Millau in France. It the tallest viaduct (341m) in the world and it is 2.5 kilometer long. I would love to see it in future.
This building is not open for public. If you try to enter, you will be stopped by this dude.
I could see it from an aeroplane.
