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 timewhen 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 structureat 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.On May 1, 1931, the president of the United States, Herbert Hoover, took part in the opening ceremonies.He pressed a button that turned on the lights, officially opening the building.At the time, Hoover was in Washington, D.C., not New York.Today, more than 4 million people visit the Empire State Building each year.About 60 percent of the visitors are from overseas.The Empire State Building has observation areas on two floors.The first, on the 86th floor, is an open air space that surrounds the building's spire.It provides 360-degree views of the New York City skyline.Building officials say that on a clear day, visitors to the newly designed observatorycan see past up to 120 kilometers in the distance.Night-time visitors can take a new, high-speed elevator up to the 102nd floor until 1:15 in the morning.Elevator riders should take note of the building's lighting on the way up.The lights change colors daily to celebrate different holidays or people.On the way up, you can now visit new exhibits on the building's second floor.Among these are a model of the moving hand used by King Kong in the 1933 movie of the same name.In the film, King Kong climbs the Empire State Building.The creature is attacked by military planes and falls to his death.The price to visit the 86th floor observatory is $38 per person,while the cost to ride all the way to the top is $58.A major New York City developer paid for the $165 million remodeling project.
