The Empire State Building is a 102-story landmark in New York City, United States, at the intersection of Fifth Avenue and West 34th Street. It is 1,250 ft (381 meters) tall. Its name is derived from the nickname for New York, the Empire State. It stood as the world's tallest building for 40 years, from its completion in 1931 until construction of the World Trade Center's North Tower was completed in 1972. Following the destruction of the World Trade Center in 2001, the Empire State Building once again became the tallest building in New York City. The Empire State Building has been named by the American Society of Civil Engineers as one of the Seven Wonders of the Modern World. The building and its street floor interior are designated landmarks of the New York City Landmarks Preservation Commission, and confirmed by the New York City Board of Estimate. It was designated as a National Historic Landmark in 1986. In 2007, it was ranked number one on the List of America's Favorite Architecture according to the AIA. The building is owned and managed by W&H Properties. The Empire State Building is currently the third tallest skyscraper in the United States (after the Willis Tower and Trump International Hotel and Tower, both in Chicago), and the 15th tallest in the world. It is also the fourth tallest freestanding structure in the Americas. The Empire State Building has one of the most popular outdoor observatories in the world, having been visited by over 110 million people. The 86th-floor observation deck offers impressive 360-degree views of the city. There is a second observation deck on the 102nd floor that is open to the public. It was closed in 1999, but reopened in November 2005. It is completely enclosed and much smaller than the first one; it may be closed on high-traffic days. Tourists may pay to visit the observation deck on the 86th floor and an additional amount for the 102nd floor. The lines to enter the observation decks, according to the building's website, are "as legendary as the building itself:" there are five of them: the sidewalk line, the lobby elevator line, the ticket purchase line, the second elevator line, and the line to get off the elevator and onto the observation deck. For an extra fee tourists can skip to the front of the line. The Empire State Building Run-Up is a foot race from ground level to the 86th-floor observation deck that has been held annually since 1978. Its participants are referred to both as runners and as climbers, and are often tower running enthusiasts.
