The burial mound of King Wonseong, 38th king of Silla, lies close to Bulguksa. In 780, Wonseong and his friend Kim Yangsang fought the rebel Kim Ji-jeong. As King Hyegong died in the rebellion, Kim Yangsang took over the throne as the King Seondeok. His successor was Wonseong in the year 785. In 787 he let his title be known to the Chinese emperor, through the sending of tributes. A tradition that would be followed by Korean kings for the next centuries. From 788 King Wonseong introduced the civil service examinations from the Chinese Tang dynasty. King Wonseong died in 798, and his grave is surrounded by a stone wall, with the edges comprising of 12 stones showing the complete Chinese zodiac. By the grave are stone columns, statues of academics (Muninseok), warriors (Muinseok) and lions (Dolsaja). The statues of the warriors appear to have the facial features of European or Arabian origin and wearing turbans. The four guarding lions are all facing the grave with large grins.
