  High Quality Content by WIKIPEDIA articles! The word "skyscraper" originally was a nautical term referring to a small triangular sail set above the skysail on a sailing ship. The term was first applied to buildings in the late 19th century as a result of public amazement at the tall buildings being built in Chicago and New York City. The first skyscraper was for many years thought to be the Home Insurance Building built in Chicago, Illinois in 1885. More recent evidence points to New York's Equitable Life Assurance Building built in 1870 preceding the Chicago building by 15 years and was the first office building built using a skeletal frame. The structural definition of the word skyscraper was refined later by architectural historians, based on engineering developments of the 1880s that had enabled construction of tall multi-storey buildings. This definition was based on the steel skeleton -as opposed to constructions of load-bearing masonry, which passed their practical limit in 1891 with Chicago's Monadnock Building. Philadelphia's City Hall, completed in 1901, still holds claim as the world's tallest load-bearing masonry structure at 167 m (548 ft).
