What was the first building in the world to have more than 100 floors?

The Empire State Building is a 102-story skyscraper located on Fifth Avenue between West 33rd and 34th Streets in Midtown, Manhattan, New York City. It has a roof height of 1,250 feet (381 m), and with its antenna included, it stands a total of 1,454 feet (443.2 m) tall. Its name is derived from the nickname for New York, the Empire State. It stood as the world's tallest building for nearly 40 years, from its completion in early 1931 until the topping out of the original World Trade Center's North Tower in late 1970. Following the September 11 attacks in 2001, the Empire State Building was again the tallest building in New York, until One World Trade Center reached a greater height in April 2012. The Empire State Building is currently the fifth-tallest completed skyscraper in the United States and the 34th-tallest in the world. It is also the fifth-tallest freestanding structure in the Americas. When measured by pinnacle height, it is the fourth-tallest building in the United States.

The construction was part of an intense competition in New York for the title of "world's tallest building". Two other projects fighting for the title, 40 Wall Street and the Chrysler Building, were still under construction when work began on the Empire State Building. Each held the title for less than a year, as the Empire State Building surpassed them upon its completion, on April 11, 1931, 12 days ahead of schedule, just 410 days after construction commenced.
