Daegu-myeon of Gangjin-gun was the primary site of Goryeo dynasty celadon production between the 9th and the 14th centuries. Covering approximately 150 acres of land in nine villages, the area has been designated as the National Historical Site since 1963, and continues to protect its 180 fire kilns and maintain the sophisticated art of celadon production. Meanwhile, celadons produced in this area have also been designated as national treasure, and regarded highly worldwide for their artistic value, so much so that some are preserved in the Louvre Museum in France.
