The world’s tallest [man-made anything] opened on Monday.
Fireworks erupted from many floors of the building, but some appeared as if they came from tubes that stretched the entire height (these were probably stroboscope lights). Watch the show on YouTube.
Known for years as Dubai Tower (burj in Arabic means tower), the developers, possibly under pressure from Dubai central government, changed the name to Burj Khalifa the day before its grand opening on Monday, January 4, 2010.
Sheikh Khalifa bin Zayed Al Nahyan is the president of the United Arab Emirates, and the emir of Abu Dhabi. In December 2009, Abu Dhabi “donated” $10 billion to Dubai to help pay off loans undertaken by the state-owned Dubai World.
Interestingly, though, Dubai World does not own and did not develop the skyscraper. (Dubai World is best known for the Palm Islands.)
Find more photos in the Flickr group, Burj Dubai. The replacement group, Burj Khalifa, just started and has six photos as of this writing. And, as usual, the article on Wikipedia is a great place to learn more.
