Underwater Tomb of King Munmu

Overview

Daewangam (Great King Rock) is a small rocky islet just offshore in the East Sea, traditionally identified as the underwater burial site of King Munmu of Silla (r. 661–681), who requested that his ashes be scattered at sea so he could become a dragon to guard Korea's coast. It is one of the most unique royal burial sites in the world.

Highlights

• Sea Burial Legend: Munmu's dying wish — to be reborn as a sea dragon to protect Silla — makes this one of Korea's most romantic historical stories.
• Rocky Islet: A cluster of flat rocks visible from the shore, with a cruciform channel cut into the stone believed to have held the king's remains.
• Sunrise Spot: The site faces directly east, and the sunrise over the islet is a popular photography moment.

History

King Munmu unified the three Korean kingdoms and, upon his death in 681 CE, was cremated with his ashes placed in the sea according to Buddhist customs. The underwater channel in the rocks was rediscovered in the 20th century and is now protected as Historic Site No. 158. The nearby Gameunsa temple was built by his son to honour his spirit.

Visitor Tips

• Viewpoint only: You cannot walk to or on the islet — it's viewed from the coastal path and Gameunsa site.
• Combine with Gameunsa: The two sites are 1 km apart along the coast road.
• Duration: 15–30 minutes.
