The 31st Koryo king, Kongmin reigned between 1352 and 1374 and his tomb is the best preserved and most elaborate in the country. It is richly decorated with traditional granite facing and statuary, including sheep statues (in honour of his Mongolian wife, also buried here) and plenty of vaguely Aztec-looking altars. It’s a very secluded site, about 13km west of Kaesong.
