Janggundo is a small uninhabited island located in the middle of in Jungang-dong, Yeosu, South Jeolla Province, South Korea.[1] [2] The island has also gone by the name Chamgyeongdo and Daeseom . It is roughly circular, and has a coastline of 600m (2,000feet) and area of 17851m2.
While the island is uninhabited, fishermen occasionally ride their boats to the island, and ferries have sometimes moved people over there for sightseeing. However, all ferry services to the island were discontinued in 2015, making the island difficult to access for people who do not own a boat.
The island gets its name from a naval officer who was associated with the island. He built defensive barriers on and around the island for protection against wokou (Japanese pirates) around 1497. There is a legend that three dragons are constantly fighting over ownership of the island. Each dragon is represented by nearby geographical features: the mountain Yeamsan, the island Dolsando, and the island Gyeonghodo.
The area was being gradually eroded due to fast currents. To slow this process, the city built a stone wall around its coast in 2005.
