King Munmu was the first ruler in Korean history to receive a formal cremation burial.
The central rock basin contains a flat stone structure often hypothesized by researchers to be the actual burial container for the king's ashes.
Local belief holds that the king transformed into a dragon upon death to fend off Japanese pirates.
The site is historically recorded in the Samguk Yusa as the final resting place of the 30th monarch of Silla.
The underwater currents within the rock formation are engineered to minimize wave impact on the central stone pedestal.
The Tomb of King Munmu, or Daewangam, is a submerged royal burial site located approximately 200 meters off the coast of Bonggil Beach in Gyeongju. King Munmu of Silla requested his remains be cremated and interred in the East Sea to protect the kingdom as a dragon. The tomb consists of a naturally formed submerged rock formation arranged around a central pool. Underwater research has identified a cross-shaped waterway designed to allow seawater to circulate around the central burial spot. This site serves as a physical manifestation of Silla-era Buddhist-influenced state ideology and naval defense philosophy. The area remains an active site for shamanistic prayer and ritual offerings.
The shoreline directly opposite the islet on Bonggil Beach provides the clearest line of sight for long-exposure photography.
Bring high-quality binoculars or a telephoto lens to observe the rock structure clearly from the shore.
Visit during the early morning to capture the sunrise behind the islet, which is a significant cultural motif in Gyeongju.
Be aware that the beach is composed of small stones rather than fine sand, so wear sturdy footwear.
Do not attempt to swim out to the islet, as the currents surrounding the rock formation are strong and dangerous.
Maintain a respectful distance from local residents performing shamanistic rituals on the beach.
