The skyscraper is a very tall building. Although there is no official definition of a skyscraper, it is sometimes considered that the height of a building of 150 meters qualifies it to be called a skyscraper. The look and feel is another characteristic of the building that qualifies it to be called a skyscraper. Chicago is the birthplace of skyscrapers.

Height based on altitude measurements of wind.
History and development of the skyscraper
The term skyscraper (skyscraper) was used in the eighteenth century to denote the tall shafts of English ships. From the beginning of the twentieth century and throughout the modern and contemporary era, the term skyscraper has referred to a specific type of building, the tallest construction designed by humans: the modern tower with a metal structure.
A skyscraper is any building with a height of more than 100 meters. However, height is not limited to metres, skyscrapers are usually considered to be buildings over 15 stories high (in the beginning the Wainwright Ten-story Building was considered the first skyscraper). Buildings of this definition exist (even in large quantities) in most of the world's cities, which is why a number of leading architects have come together at the International Council of Architecture (World Federation of Great Towers) to give more distinction between multi-story buildings and skyscrapers. Real (which are still very few in the world).
The Industrial Revolution and the introduction of machinery led to the construction of tall towers of stone, glass and steel on the island of Manhattan in New York City. Subsequently, these buildings reached hundreds of meters (100 storeys) high, such as the Empire Bldg. and the World Trade Center towers.
Beginning in 1920 in New York, a real competition began in which hundreds of finance companies, and thousands of people, between architects and professionals, participated in the construction of the tallest building in the world.
This competition for heights did not end with the end of World War II, and twenty years later it reached its climax and the line of business moved from the city center (full of buildings) to the financial market district in the far south of Manhattan (Lower Manhattan). Here between 1966 and 1973 the twin towers were built: the World Trade Center.
