UNESCO tentative list for S. Korea

UNESCO World Heritage Center has a transparent posting of the tentative world heritage sites for each country. As I understand it, much paperwork is needed to even apply to put one's own country's site on the tentative list, and many tentative sites remain just that ... tentative for many years. Here is the tentative list with the most recent updates being January 24, 2017. Note that South Korea added one more (Stone Buddhas and Pagodas at Hwasun Unjusa Temple) since the last updating of the UNESCO website.
