Skyscraper

A skyscraper is a very tall high-rise building, usually more than 152 metres (500 feet) in height. Most skyscrapers are built in urban areas such as cities, and they are very common in the central business district (also called downtown) areas of many large cities including New York City, Chicago, London, Paris, Sydney, Beijing, Berlin, Toronto, Moscow, Hong Kong and Tokyo. Skyscrapers are common in downtown districts where it's more economical to build up instead of out.
