Incheon is where Korea met the world — and where the world kept arriving uninvited. Walk Bronze Age dolmens and Goryeo palaces on Ganghwa, then trace the 1883 treaty port, the Japanese banks, and MacArthur's 1950 amphibious gamble at Green Beach.
UNESCO-listed northern-type table dolmen from around 1000–300 BC, capstone 6.5m wide and roughly 50 tonnes. Free, open grounds year-round; the adjacent Ganghwa History Museum (3,000 won) explains the 150-plus dolmens scattered across the island.
Traditional five-day-market descendant beside the old town wall, running since the Joseon period as the island's trade hub. Second floor food alley serves Ganghwa specialities — sun-dried croaker, ginseng-chicken and hand-cut noodles for 8,000–15,000 won.
The refuge capital where the Goryeo court ruled for 39 years (1232–1270) while resisting the Mongol invasions, and where the Tripitaka Koreana woodblocks were carved. Ruins, Joseon-era magistrate hall and Oepyeongjeon archive rebuilt. Entry 900 won.
Korea's oldest Anglican church, built 1900 as a Confucian-style wooden hall with a hipped tiled roof, ship-hull nave and a bodhi tree in the courtyard — deliberate architectural syncretism by Bishop Charles Corfe. Free entry, still an active parish.
Two-floor museum on Operation Chromite, the 15 September 1950 landing of 75,000 UN troops across Red, Green and Blue Beaches that cut North Korean supply lines and retook Seoul in eleven days. Dioramas, landing craft, tide charts. Free entry, closed Mondays.
Coastal battery where Korean gunners fired on the USS Colorado's marines in the 1871 Shinmiyangyo and on the Japanese warship Un'yō in 1875 — the incident that forced open the Ganghwa Treaty. Cannon emplacements and shell-scarred pine still stand.
Korea's first public municipal museum, founded 1946 in the old Japanese consulate. Collections cover the Jemulpo treaty port, the 1904 naval battle in which the Russian cruiser Varyag was scuttled offshore, and Incheon's Chinese labour migration. 500 won.
Marks the SS Gaelic's departure from Jemulpo on 22 December 1902 carrying 121 Koreans to Hawaii's sugar plantations — the first organised emigration in Korean history. Passenger manifests, plantation contracts, picture-bride letters. Free, closed Mondays.
Housed in the 1899 Japanese First Bank branch, a stone Renaissance-revival building that issued the currency used to absorb Korea's economy. Exhibits on the 1883 port opening, the Gyeongin Line — Korea's first railway, 1899 — and port modernisation. 500 won.
The 1884 Qing concession ran uphill from the port; the stone stairway still divides the former Chinese and Japanese quarters, with paired stone lanterns marking the boundary. Shandong-descended families here have run restaurants for four generations.
Set in the 1908 Gonghwachun restaurant building where Shandong dockworkers' noodles became Korea's national comfort dish. Six galleries trace the Chinese diaspora, the 1950s flour-aid era and the black-bean sauce's Korean adaptation. 1,000 won, closed Mondays.
Sinpo Market began in the 1890s as the treaty port's vegetable market serving Japanese, Chinese and Korean residents — Korea's first mixed-nationality market. Nearby Dapdong Cathedral (1897, rebuilt 1937) is Incheon's oldest Catholic parish.
