The Cheongju Early Printing Museum stands on the excavated site of Heungdeoksa Temple, where Buddhist monks used movable metal type to print the Jikji in 1377 — making it the oldest surviving book printed with movable metal type in the world, predating Gutenberg by 78 years. The museum holds over 600 artefacts related to Korean printing history and explains in detail the technology behind movable metal type and how it was developed in Korea centuries before Europe.
The original Jikji is held in the Bibliothèque nationale de France (a fact that causes ongoing diplomatic friction), but the museum displays high-quality replicas and walk-through exhibits on the printing process. There is a demonstration area where visitors can try pressing their own print from wooden blocks, and regular demonstrations of traditional Korean bookbinding. The museum is free to enter and well-signposted from central Cheongju.
