The tombs are believed to be ones of those related to the royal family in the late period of Koryo Kingdom (918-1392) for their sizes, structures and remains.

The round-shaped cluster was built on a slope of the mountain.

Each of the tombs has stone pieces piled up in its lower part, with stone parapets and stone-made animal sculptures set up around it. The tombs are situated from the west to the east.

The Myongrung Cluster consisting of three tombs is located at the foot of a mountain about one kilometer west of the Mausoleum of King Wang Kon.

One of the three tombs was found to be Chung Mok's, the 29th king (1345-1348) of Koryo Kingdom.

The one-chamber tombs have flat ceilings with stars pictured on them. Their walls were built with plain rocks decorated with paintings.
