Incheon Landing Memorial Hall honors a pivotal moment in the city’s history and in the country’s push for freedom. More than 75,000 troops and 250 ships took part in MacArthur’s amphibious landing at Incheon, like a wall of metal and guns approaching land. The Memorial Hall offers photos and newsreels from the landing, as well as displays explaining some of the weaponry used. It also features something frequently overlooked: The statistic that, in all, 16 countries joined the fight for South Korea—their flags fly outside the hall. This is a must-stop for history buffs.
