The Mon-Sol Project is a joint academic project implemented by the Archaeology and History Division of the National Museum of Korea, along with the National Museum of Mongolia and the Institutes of History and Archaeology at the Mongolian Academy of Sciences.

• The Mon-Sol Project aims to track the formation of various ancient cultures in different Asian regions by investigating historical sites and shedding light on Korea’s cultural identity by comparing Korea with other cultures. After signing the first joint expedition agreement in 1997, the project conducted expeditions to five historical sites, special exhibitions based on the outcomes of the investigations, and numerous symposiums. The current project, implemented under the fourth joint expedition agreement, involves excavating Xiongnu historical sites.
• Under this project, sixteen field surveys and excavations have been conducted at five historical sites, including the Xiongnu tombs in Duurlig Nars, Mongolia. The findings from the Mon-Sol Project have profound academic significance. The Xiongnu tombs in Duurlig Nars, have been recognized as representative Mongolian tombs.
• Findings are disclosed to the public through several exhibitions, including the special exhibition, "Korean-Mongolian Joint Expedition in Mongolia", and the themed exhibition, "Duurlig Nars". The project has also produced ten reports and sourcebooks, starting from the expedition report: Uglugchingol Site, Mongolia.
• The Mon-Sol Project involves expeditions at the Goa Tov site in Tuv Aimag, 120 km from Ulaanbaatar. The Goa Tov site came into the spotlight when building foundations from the Xiongnu period were discovered for the first time in the area. This discovery is significant because it provided data to compare Xiongnu historical sites to the historical sites of ancient China. Investigation at the Goa Tov site will continue until the end of this year.
• The Mon-Sol project awaits the signing of the fifth joint expedition agreement. The fifth agreement is expected to look back at the achievements made through the project over the last 20 years and find a direction for the project’s future.
