This area is a UNESCO World Heritage site. From whc.unesco.org The Gyeongju Historic Areas contain a remarkable concentration of outstanding examples of Korean Buddhist art, in the form of sculptures, reliefs, pagodas, and the remains of temples and palaces from the flowering, in particular between the 7th and 10th centuries, of this form of unique artistic expression. This is the Tumuli Park, in the Tululi Park Belt. It consists of three groups of Royal Tombs. Most of the mounds are domed, but some are half-moon or gourd. These contain double wooden coffins, covered with gravel. Excavations have found rich graves of goods of gold, glass, and fine ceramics.
