A significant historical event of the Goryeo period is the production of the first woodblock edition of the Tripiṭaka called the "Tripitaka Koreana". Two editions were made, the first one completed from 1210 to 1231, and the second one from 1214 to 1259. The first edition was destroyed in a fire, during an attack by the Mongols in 1232, but the second edition is still in existence at Haeinsa in Gyeongsang. This edition of the "Tripitaka" was of high quality, and served as the standard version of the "Tripitaka" in East Asia for almost 700 years.
