the Swiss Re Tower

Từ điển Oxford Advanced Learner 8th

the Swiss Re Tower [the Swiss Re Tower] BrE NAmE
a tall office building in the City of London, the head office of the Swiss Reinsurance Company, which opened in 2004. Its unusual round shape which narrows to a point at the top has led to it being called the Gherkin (= a small pickled cucumber). It was designed by Norman Foster and has many features which mean that it uses 50% less energy than a traditional office building.
