In May 2007, a fisherman caught a bay octopus tightly grabbing a celadon dish in his fish trap. The discovery near Taean's Daeseom Island in South Chungcheong Province led to a historic excavation of valuable underwater heritage carried out by the National Research Institute of Maritime Cultural Heritage in 2007 and 2008.
The excavation uncovered a cargo boat carrying several thousand celadon articles, wooden tags inscribed with information about the articles, general goods used by the seamen, and a skeleton of a Goryeo man who was trapped under his cargo during the wreck. The items had been submerged for about 900 years.
The institute, along with the Administration of Gangjin County, is holding a special exhibition titled "Goryeo Celadon Shipwreck" at the National Palace Museum of Korea in Gyeonggbok Palace, Seoul.
The exhibition is part of the institute's efforts to seek restoration of the sea routes used by Goryeo cargo boats carrying celadon works.
A total of 740 pieces of the relics found are on display, including other ceramics found in Gangjin, South Jeolla Province.
