2013: The year of the super-tall skyscraper

While 2013 didn't see the completion of a mega tower like Burj Khalifa, it was a near-record-setting year in terms of the number of super-tall skyscrapers completed.

Led by the 82-story, 1,166-foot JW Marriott Marquis Hotel Dubai Tower 2, a total of 73 buildings of 200 meters or greater height were built in 2013. It was the second-busiest year ever, behind only 2011, when 81 super-tall projects opened, according to a report by the Council on Tall Buildings and Urban Habitat (CTBUH).

Last year also saw the completion of nine 300-meter-plus towers. In fact, nearly half (47%) the world's 77 300-meter-plus skyscrapers were completed during the past four years.
