The Burj Khalifa, the world’s 828 meter tallest building, is illuminated during the official opening ceremony in Dubai, United Arab Emirates. The Burj Khalifa’s owner said Monday, February 8th 2010, the observation deck of the world’s tallest tower has been unexpectedly shut down, disappointing visitors and marring the spire’s reputation just a month after it opened. The precise cause of the $1.5 billion Dubai skyscraper’s closure remained unclear. |
