Begun in 1790, Mingun Paya would have been the world’s biggest stupa if it had been completed. Work stopped in 1819 when King Bodawpaya died, and at that point only the bottom third of the structure was finished. What's there is still huge: a roughly 240ft cube on a 460ft lower terrace. It's often described as the world’s largest pile of bricks. There's a steep staircase to the top, though since the 2012 earthquake, you can only climb midway for amazing views of the countryside.
For added drama, there are several deep cracks, caused by the massive 1838 earthquake.
