Before Ulsan became an industrial powerhouse
Ulsan is known for cars and shipbuilding, but the Dalcheon iron site in Buk-gu reveals a much older industrial story. The festival organizer describes *soeburi* as Korea's traditional process of smelting iron. Mining ended at Dalcheon in 2002; a heritage park and interpretive exhibits now preserve the story.
Inside the interpretation center
Exhibits introduce the history of iron, mine photographs, historical shafts, videos and a reconstructed iron-furnace experience. Rather than expecting a live demonstration, consider how the raw material, the workers and the craft connect to modern industry. Specific activities or guided tours may not run on every visit.
