This is the tomb of King Jinheung (540-576), the 24th king of Silla. The grandson of King Jijeung, King Jinheung established the base of unification of the Three Dynasties by taking up the Hangang River area occupied by the Goguryeo Dynasty. He expanded the territory to the Nakdonggang River area south of Silla and to the Hamheung Plain on the north. Because Jinheung is the king who occupied the largest territory through the history of Silla, steles named “Sunsubi” were erected in some regions he newly obtained to commemorate his achievements. He ordered Geochilbu to write Guksa (National History) and constructed Hwangnyongsa Temple, the biggest temple built during the Silla Period. Furthermore, he organized Hwarangdo (flower of youth band), which was the key organization leading the unification of the Three Dynasties. As a mound-type tomb with height of 5.8m and diameter of 8m, it is supported by the unpolished stones put along its base. Its scale is not that big for the king who had the best performance among the kings of Silla. Another assertion is that the second one among the tombs in Seoak-ri is the tomb of King Jinheung because he became king after King Beopheung.
