尚寧王
King Eiso (r. 1260–1299) ruled Chūzan from Urasoe, and is entombed near the northwest cliff of the castle. His mausoleum contains three stone coffins from China, possibly from Fujian; it is believed that Eiso is buried in the largest one, his father and grandfather in the other two. The coffins are decorated with birds, flowers, deer, shishi (lion-dogs), and various Buddhist images, along with dragons and phoenixes on the lids, which are designed to look like tiled roofs. Eiso lived in the 13th century, however, based on the style of designs and decorations on the coffins, archaeologists believe these to be of later, 15th-century, construction. King Shō Nei (r. 1597–1620), is also entombed here.
