Jeju was the independent Tamna Kingdom until 1404, then a Joseon exile colony, then the site of Korea's most contested 20th-century tragedy. Three days of walled compounds, stone grandfathers and memorial halls trace all of it.
Three ground holes where Go, Yang and Bu — the founding demigods of the Tamna Kingdom — are said to have emerged. A state-designated Historic Site since 1964, with a Confucian shrine hall added in 1526. Open 09:00–18:00, closed Lunar New Year.
The Joseon-era provincial governor's compound, razed by fire in 1434 and rebuilt, then flattened during Japanese rule. Reconstructed 1999–2002 from excavation data and the Tamnasunryeokdo paintings. Historic Site No. 380.
A surviving 100m stretch of the Joseon city wall that once ringed the old town, built up in 1512 and largely demolished by the Japanese in 1925 to fill in Sanjicheon harbour. Free, open ground, interpretive panels in Korean and English.
Opened 2001; the Tamna gallery holds Bronze Age dolmen finds, Goryeo celadon dredged from the strait and Joseon exile records. The prehistory room covers the Gosan-ri site — among the oldest pottery finds in Korea, c. 10,000 BC.
Memorial to the 1948–54 uprising and suppression in which an estimated 30,000 islanders — a tenth of the population — died. Opened 2008 after the 2003 presidential apology. The unnamed 'Baekbi' lies blank until a name is agreed.
Twenty concrete aircraft hangars built by forced Korean labour from 1926 for the Imperial Japanese Navy, used to bomb Nanjing in 1937. Registered Cultural Heritage No. 39. Open farmland, walkable, no gate.
Opened 1984 next to Samseonghyeol; reconstructed thatched Jeju houses, haenyeo diving gear, funeral biers and the tools of a subsistence island economy before the 1960s tangerine boom.
The stream that fed the walled town, culverted over in 1966 for a market building and re-opened in 2002. The restored Gomi Bridge area marks where the 1901 Yi Jae-su uprising crowds gathered against Catholic tax collectors.
Opened 2006 across 3.3 km² of the Gotjawal forest; galleries of dolhareubang stone grandfathers, traditional stone walls and the Seolmundae Halmang creation myth of the grandmother goddess who formed the island.
The walled seat of Jeongui-hyeon county from 1423 to 1914, still inhabited. Important Folklore Cultural Heritage No. 188 — thatched roofs roped against typhoons, olle stone entry lanes and the 1000-year-old zelkova by the magistrate's hall.
The Confucian county school first founded in 1392 and moved to its present Yongdam site in 1827. Daeseongjeon hall holds tablets to Confucius and Korean sages; semi-annual Seokjeon rites are still performed in spring and autumn.
A working diving village where the stone bulteok — the circular windbreak fires where haenyeo changed and ranked themselves by skill — survive on the shore. The practice was UNESCO-listed in 2016; most active divers are now over 70.
