At one of the oldest burial sites in the southern part of the country, there were once more than 100 burial mounds dating back to the Gaya Kingdom (6th c.) here. Although part of the mound was destroyed inadvertently by construction in the area in 1969, it has since been designated a historical site. Now over 9,000 relics (including pieces of pottery and ironware) have been excavated from the surrounding area. Although many of those finds are no longer here -- they're now part of the Busan National Museum's collection -- there is also a museum on-site housing some of the unearthed treasures. A few of the tombs have since been re-created.
