The vast majority of islands in the world are either a country in their own right or part of a single larger country. This is a list of those few islands whose land is divided between two or more countries or territories. They are mostly, though not all, among the larger islands in the world. In many cases (e.g. Ireland, Cyprus, Timor) this division has been the source of much dispute.

[edit] Divided among three countries

• Borneo - Between Indonesia (72%), Malaysia (27%), and Brunei (1%)
• Cyprus - see below
• Treriksröset - the boundary cairn at the tripoint of  Norway,  Sweden and  Finland is 10 metres from the shore of Lake Goldajärvi/Koltajauri, and hence arguably a tiny artificial island.

[edit] Historically divided islands

• Other islands have been divided by an international border in the past but are now unified. Notable examples include:
  • Great Britain - Divided among England, Scotland and Wales, but since 1707 all part of the United Kingdom
  • Saint Kitts - Divided between England and France in 1626, but from 1713 became fully British until independence in 1983.
  • Sakhalin - Divided between Imperial Russia/Soviet Union and the Empire of Japan from 1905 to 1945; subsequently wholly part of the Soviet Union/Russian Federation.
  • Ankoko Island in the Cuyuni River on the border between Venezuela and British Guiana (now Guyana) was shared until Venezuela annexed the eastern half in 1966 as part of an ongoing border dispute.
  • Zhongchan Dao in the Pearl River Delta was divided between China and Macau from the Treaty of Tientsin in 1862 until Macao reverted to China in 1999.
• A different type of historical change occurred on Vozrozhdeniya Island in the Aral Sea. It is split by the border between Uzbekistan and Kazakhstan, which became an international frontier in 1991 with the dissolution of the Soviet Union; but by 2002, the island had become a peninsula owing to the falling water-level in the Aral Sea.

[edit] See also

• Condominium (international law) - land jointly administered by two states, rather than divided between them.
• List of territorial disputes - includes many islands claimed by multiple countries, but administered by one.
• Green Island (Fortune), Newfoundland - island whose sovereignty is uncertain between  Canada (administering) and  France (through Saint-Pierre and Miquelon).

[edit] National

The Four Corners is the only point in the United States of America where four states meet: Colorado, Utah, New Mexico, and Arizona meet at right angles.

There has been an analogous Four Corners in Canada at 60° N 102° W since the creation of Nunavut in 1999; it meets Saskatchewan at a point, with Manitoba and the Northwest Territories at the other corners. Before 1999 this was a tertiary quadripoint, with Manitoba, Saskatchewan, and the then existing Northwest Territories districts of Mackenzie and Keewatin..

Four provinces of the Philippines meet at a point on Mindanao island, probably at one of the three peaks of Mount Apo: Bukidnon, Davao del Norte, Davao del Sur, and Cotabato.

There are two quadripoints in Switzerland where three cantons meet. At each, a practical exclave of one canton touches its parent, while two other cantons touch each other. One is near 47°24′51″N, 7°22′33″E, where the municipality of Roggenburg is cut off from its parent Basel-Country by Jura to the south and an exclave of Solothurn to the north. The other is near 47°19′20.5″N, 7°33′30″E where Jura again touches Solothurn, cutting off the municipality of Schelten from its parent canton of Bern.^[50]

[edit] United Kingdom

An analysis of county quadpoints in the United Kingdom is complicated by the fact that the borders and numbers of counties have changed several times in the last century (see Administrative counties of England). However, through it all there has only been one true quadpoint; it lies just south west of Stamford – where Rutland, Lincolnshire, Cambridgeshire and Northamptonshire meet. (52°38′25″N, 0°29′40″W)

Following the changes of 1974, the Stamford quadpoint was unchanged. The 1995 Unitary Authority boundary changes mean that the Cambridgeshire side of the point is now officially in the Unitary Authority of Peterborough, but the situation is otherwise unchanged.

In addition there are a few near misses. Near East Grinstead, the East Sussex-West Sussex-Surrey and East Sussex-Surrey-Kent tripoints are only a mile apart. Similarly the Staffordshire-Warwickshire-Leicestershire and Warwickshire-Leicestershire-Derbyshire tripoints are again around a mile apart. And until 1965, the two tripoints formed by Gloucestershire, Oxfordshire, Wiltshire and Berkshire near Lechlade came very close to one another. (51°41′20″N, 1°40′37″W). Near Evenlode in Gloucestershire, there is a "four-shire stone", but it lies at the Gloucestershire-Oxfordshire-Warwickshire tripoint, and around ten miles from Worcestershire.
