The Palace of Culture and Science is a notable high-rise building in central Warsaw, Poland. With a total height of 237 metres (778 ft), it is the second tallest building in both Warsaw and Poland, the sixth tallest building in the European Union and one of the tallest on the European continent. At the time of its completion in 1955, the Palace was the eighth tallest building in the world, retaining the position until 1961; it was also briefly the tallest clock tower in the world, from 2000 until the 2002 installation of a clock mechanism on the NTT Docomo Yoyogi Building in Tokyo, Japan.

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.
