The Empire State Building is an iconic New York skyscraper built in 1931. Made from concrete and steel and, at 1454 feet (443.2m) from floor to the top of the spire, it was the tallest building in the world for over forty years, surpassed by the North Tower of the original World Trade Center in 1972. It is an example of Art Deco architecture, and is undergoing a retrofit to become more eco-friendly and energy efficient. Designated a National Historic Landmark in 1986, and named as one of the Seven Wonders of the Modern World and the AIA’s list of America’s Favourite Architecture, it has also prominently featured in popular culture, often as part of an establishing shot for New York City, most notably featuring in the 1933 move King Kong and its 2005 remake. It is floodlit in different colours for different seasonal holidays and events, such as green for St. Patrick’s Day, red, white and blue for Independence Day, or blue for when Barack Obama won the 2012 Presidential Election.
