Tripitaka Koreana

The Tripiṭaka Koreana is a Korean collection of the Tripiṭaka (Buddhist scriptures), carved onto 81,258 wooden printing blocks in the 13th century. They are currently located at the Buddhist temple Haeinsa, in South Gyeongsang Province, South Korea. It is the oldest intact version of Buddhist canon in Hanja script. It contains 1,496 titles, divided into 6,568 books, spanning 81,258 pages, for a total 52,330,152 Hanja characters. It is often called the Palman Daejanggyeong ("Eighty-thousand Tripitaka") due to the number of the printing plates that comprise it. It is also known as the Goryeo Daejanggyeong (Goryeo dynasty Tripitaka).

Each wood block (page) measures 24 centimetres in height and 70 centimetres (9.4 in × 27.6 in) in length. The thickness of the blocks ranges from 2.6 to 4 centimetres (1.0–1.6 in) and each weighs about three to four kilograms (6.61 - 8.81 lbs). The woodblocks would be almost as tall as Paektu Mountain at 2.74 km (1.70 mi) if stacked and would measure 60 km (37 mi) long if lined up, and weigh 280 tons in total. The woodblocks are in pristine condition without warping or deformation despite being created more than 750 years ago.

The Tripiṭaka was designated a National Treasure of South Korea in 1962, and inscribed in the UNESCO Memory of the World international register in 2007. Historically the Tripiṭaka was closed except for Buddhist events and scholars but 2021 it was opened to members of the public who preregister.
