Wooden plates with Goryeo-era inscriptions have been found in Mado near the Taean Peninsula, where a sunken ship carrying celadon was discovered.

The Cultural Heritage Administration says inscriptions on 64 wooden and bamboo plates found in waters off Mado include the name "General Kim Sun-young" who lived in the Goryeo Dynasty capital of Gaeseong some 800 years ago. The writings confirm that Kim procured merchandise, such as ceramic ware and pickled fish eggs, from the Jeolla provinces.

The administration says that based on the inscriptions written on the plates, the celadon carrier most likely set out to sea from Jeolla in the early 13th century to deliver china, pickled fish and grains to people in the capital city but that it was shipwrecked near Mado.

It's the first discovery of wooden plates bearing Goryeo-era inscriptions. Fourteen-hundred pieces of relics including ceramics, coal and daily articles were also found on the ship.
