**Ganghwa Island** ([Korean](/source/Korean_language): 강화도), also **Ganghwado**, is an island in [Ganghwa County](/source/Ganghwa_County), [Incheon](/source/Incheon), South Korea. It is in the [Yellow Sea](/source/Yellow_Sea) and in an [estuary](/source/Estuary) of the [Han River](/source/Han_River_(Korea)).

The island is separated from [Gimpo](/source/Gimpo) (on the South Korean mainland) by a narrow channel spanned by two bridges, and from [Kaesong](/source/Kaesong) (Gaeseong) in [North Korea](/source/North_Korea) by the main channel of the Han River. It offers some of the closest views in the South of North Korean villages, which can be seen on clear days from less than two kilometers.[1]

It is strategically located, controlling access to the river, which runs through former [Joseon](/source/Joseon) and South Korea's capital, [Seoul](/source/Seoul). Its fortifications were repeatedly attacked in the [19th century](/source/History_of_Korea#Joseon_dynasty). With an area of 302.4 km2 (116.8 sq mi), it constitutes most of [Ganghwa County](/source/Ganghwa_County) (a division of [Incheon](/source/Incheon)). The island has a population of about 65,500, half of whom live in Ganghwa Town (Ganghwa-eup) in the northeast.

## Name

Before the 10th century, the island went by various names, including Haegu (해구; 海口; lit. 'mouth of the sea'), Hyeolgu (혈구; 穴口; lit. 'opening'), Gangha (강하; 江下; lit. 'below river[s]').[2]

In 940, during the [Goryeo](/source/Goryeo) period, it received its current name, which means "beautiful [town by the] river".[2]

Former [romanizations](/source/Romanization_of_Korean) include "Kang-hoa"[3] and "Kang-hwa".

## Geography

The island is in the estuary of [Korea](/source/Korean_Peninsula)'s Han River. It is South Korea's fourth-largest island, with an area of 305.75 km2 (118.05 sq mi), and has a coastline of 106.5 km (66.2 mi). Over time, land reclamation projects for agricultural purposes have increased the island's size.[2]

The island has a number of mountains. The tallest is [Manisan](/source/Manisan_(Incheon)), in the south of the island, with a height of 469 m (1,539 ft). Also on the island are Jingangsan (진강산), [Goryeosan](/source/Goryeosan), Nakjobong (낙조봉), Hyeolgusan (혈구산), and Byeollipsan (별립산).[2]

The island was originally connected to the mainland, but became separate over time via erosion. [Mudflats](/source/Mudflat) now surround the island.[2]

## History

The island was part of Ganghwa-hyeon in the early [Goryeo](/source/Goryeo) period. It became part of Ganghwa-bu in 1377. It became part of Ganghwa County in [Gyeonggi Province](/source/Gyeonggi_Province) ([Keiki-dō](/source/Keiki-d%C5%8D)) in 1914, and remained so until 1994, when it became part of Incheon Metropolitan City.[2]

The island was the site of the 1866 [French expedition to Korea](/source/French_expedition_to_Korea),[7] the 1871 [United States expedition to Korea](/source/United_States_expedition_to_Korea), the [Battle of Ganghwa](/source/Battle_of_Ganghwa),[8] and the 1875 [Ganghwa Island incident](/source/Ganghwa_Island_incident) with Japan.[9] In 1876 Korea was forced to sign with Japan the [Treaty of Ganghwa](/source/Japan%E2%80%93Korea_Treaty_of_1876), which was named for the island.[10]

## Transportation

In 1969, the [Ganghwa Bridge](https://en.wikipedia.org/w/index.php?title=Ganghwa_Bridge&action=edit&redlink=1) [[ko](https://ko.wikipedia.org/wiki/%EA%B0%95%ED%99%94%EB%8C%80%EA%B5%90)] was constructed between the island and the mainland. The bridge was replaced in 1997. The [Ganghwa Choji Bridge](https://en.wikipedia.org/w/index.php?title=Ganghwa_Choji_Bridge&action=edit&redlink=1) [[ko](https://ko.wikipedia.org/wiki/%EA%B0%95%ED%99%94%EC%B4%88%EC%A7%80%EB%8C%80%EA%B5%90)] opened in 2002.[2]

The island's turnip (*[Brassica rapa](/source/Brassica_rapa)*) has been cultivated for over 1,000 years. Its moisture content is over 90% and its main component is carbohydrate. The dark-purple, taproot vegetable has a mustardy scent and tastes like ginseng. Its seeds and the fully grown vegetable are used in folk remedies and Oriental medicine. Its leaves have vitamins, and its roots contain [tryptophan](/source/Tryptophan) and [glycyrrhizin](/source/Glycyrrhizin). Said to prevent cancer, the turnip helps cure skin diseases, digestive ailments, tuberculosis, and respiratory disease with an anti-bacterial effect.[17][18]
