Dubai has different uses as its main tourist attractions, and the Burj Khalifa, which also happens to be the world's tallest man-made structure, stands out. For one, the tallest tower in the world doubles as the world's largest LED display too, as the building's glass façade is fitted with around 1.2 million LED lights that light up to display literally any content. This feature of the Burj has been used on various occasions, such as celebrating the days marking the independence of different countries of the world.
