About this place

The Tomb of King Munmu lies offshore of Munmudaewang-myeon in Gyeongju, North Gyeongsang, and holds the thirtieth king of Unified Silla. The Encyclopedia of Korean Culture records that he was buried in the East Sea according to his will, and that the will was this: cremate him in the Buddhist manner and bury him in the East Sea, and he would become a dragon and block the Japanese raiders who came in from that sea. It is a natural rock in the water close to shore, designated a Historic Site on 24 July 1967.

    Channels on four sides

    From the rock it looks as though channels were cut on all four sides for the sea to run in and out.

    The stone at the centre

    A wide, flat stone lies lengthwise north to south at the centre of the still water inside.

    documented history

Here the grave is itself the petition. Elsewhere a person comes to ask for something; here the person buried said in advance what he would do. He would become a dragon and stop the raiders entering the East Sea.

Climb onto the rock and it looks as though channels have been cut on all four sides for the sea to run in and out, with a fairly broad stretch of still water inside. At the centre of that water lies a wide, flat stone set lengthwise north to south.

That is as far as the encyclopedia goes. Whether the will was kept, and how much of it is fact, the record does not say — and neither does this page.
