Namiseom or Nami Island (Korean: 남이섬) is a half-moon shaped river island located in Chuncheon, Gangwon Province, South Korea, formed as the land around it was inundated by the rising water of the North Han River as the result of the construction of Cheongpyeong Dam in 1944.
The name of the island originates from General Nami, who died at the age of 28 after being falsely accused of treason during the reign of King Sejo, the seventh king of the Joseon Dynasty of Korea. Although his grave was not discovered, there were a pile of stones where his body was supposed to be buried. It was believed that if someone took even one stone from there, it would bring misfortune to their house. A tour company arranged the grave with soil and then developed Namiseom into an amusement park.
