 The Goryeo period is famous for two major landmarks in Korean printmaking and paper history.One was the carving of the Tripitaka Koreana onto over 80,000 wooden blocks, which contain no errors and are still extant in their original home at Haeinsa, a Buddhist temple in Gyeongsangnam-do.It was carved twice, due to its destruction by Mongol invasions in 1232; the final version was completed in 1251.
