The Seven Sisters are a group of seven skyscrapers in Moscow designed in the Stalinist style. They were built from 1947 to 1953. At the time of construction, they were the tallest buildings in Europe, and the main building of Moscow State University remained the tallest building in Europe until 1990.

A skyscraper is a tall continuously habitable building having multiple floors. Modern sources define skyscrapers as being at least 100 meters (330 ft) or 150 meters (490 ft) in height, though there is no universally accepted definition, other than being very tall high-rise buildings. Historically, the term first referred to buildings with between 10 and 20 stories when these types of buildings began to be constructed in the 1880s. Skyscrapers may host offices, hotels, residential spaces, and retail spaces.
