Ancient Tombs Listed as UNESCO World Heritage Site

The seven Gaya Tumuli or tomb clusters dating back to Korea's ancient Gaya confederacy have been listed as a UNESCO World Heritage site.

The World Heritage Committee made the decision in a meeting in Riyadh, Saudi Arabia on Sunday. 

"The introduction of new forms of tombs and the intensification of the spatial hierarchy in the tumuli sites reflect the structural changes experienced by Gaya society during its history," UNESCO said, ensuring their "outstanding universal value." 

Built in the first to sixth centuries, the circular burial mounds are scattered around southern Korea.
