Completed in 1581, this three-storey pavilion was supposedly the work of one thoroughly crazed individual (Yu Xichun, who wanted to be able to see Běijīng from the top). It was, according to legend, built entirely at night, over a 16-year period, without the help of any other villagers.
It was certainly built by an amateur architect: there’s no foundation, and the building stones (in addition to not being sealed by mortar) are of wildly different sizes (some as large as 2m), giving it a higgledy-piggledy look that’s quite uncommon in Chinese architecture.
