As the most iconic structure in all of Dubai, the Burj Khalifa is located in Downtown Dubai and is among the tallest buildings in the world. Having been officially opened in 2009, the Burj Khalifa surpassed the second tallest structure in the globe, the Shanghai Tower, by an impressive 200 meters at the time of its opening. It took only 5 years to complete this mammoth building which has been divided into 163 floors. Paying homage to Islamic architectural motifs the Burj Khalifa is also decidedly modern. Home to the highest observation deck in the world, the views from the outdoor viewing platform is spectacular, to say the least.
