The National Research Institute of Maritime Heritage marks fifty years of underwater excavation by exhibiting zitan wood cargo from the Sinan ship and evidence of fourteenth-century East Asian trade. Visit the Maritime Relics Exhibition Hall at 136 Namnong-ro, Mokpo, Tuesday–Sunday 09:00–18:00, closed Mondays; free entry. The ministry listing's header says the show began September 14, but the description gives September 15. This discrepancy is noted rather than silently resolved. Look for Chinese characters, Phags-pa and Japanese kana markings on the wood.
