One of the great temples in Korea, Haeinsa is located in Gayasan National Park about an hour Southwest of Daegu. The temple itself is worth exploring, but the woodblocks is what makes Haeinsa truly special. The number of woodblock prints is stunning and considering that these Buddhist sutras are numerous centuries old is something to marvel at. Indeed, these treasures were commissioned during the Goryeo Dynasty. The temple and national Park are both great sites. Plan additional time getting to the temple as its a bit out of the way.
In addition to basic logistics, there are factors worth considering. Haiensa is a great temple, but by no means is it the most authentic, exceptional, or representative of Korean Buddhist temples. Its OUV lies primarily in the Janggyeong Panjeon, which was constructed to house the Tripitaka Koreana woodblocks.
