(CNN) -- China may have just topped out on its new tallest building -- the 632-meter Shanghai Tower -- but if plans underway in Changsha come to fruition, that building will hold the title until only April 2014 when the country's 838-meter Sky City is completed.
When that happens, Sky City will become the world's tallest building, beating the Burj Khalifa in Dubai by 10 meters.
While people debate the merits of building so high so quickly -- there's evidence that tall buildings often presage an economic collapse -- we wanted to take a look at other buildings that deserve browser time.
