The world famous Empire State Building opened a new visitors’ center last weekend. The new observatory can be found on the building’s 102nd floor, high above New York City. The observatory provides 360-degree views of the New York area. Visitors are able to look through large floor-to-ceiling windows that are twice as big as the old windows. The Empire State Building was built at a time when many developers were racing to be the first to complete the world’s tallest building. Ground was first broken in January 1930 and work began two months later. The building went up very fast, with workers completing framing for its structure at a rate of about four-and-a-half floors per week. When completed, the Empire State Building was just over 443 meters tall. At the time, it was the world’s tallest building.
