The United States is home to some of the world's tallest skyscrapers; eleven American buildings have held the title of tallest building in the world, and every titleholder from 1890 to 1998 was in the United States. New York City and Chicago have always been the centers of US skyscraper building. The 10-story Home Insurance Building, built in Chicago in 1885, is regarded as the world's first skyscraper; the building was constructed using a novel steel-loadbearing frame.
