The island was first claimed for Britain on 16 October 1819, formally annexed by Britain as part of the Falkland Islands Dependencies in 1908, and now as part of the separate British Antarctic Territory. The Island was claimed by Chile in 1940, as part of the Chilean Antarctic Territory. It was also claimed by Argentina in 1943, now as part of Argentine Antarctica, called by the Argentines Isla Veinticinco de Mayo in honour of their National day. The US and Russia do not recognize these claims and have formally reserved their right to claim Antarctic territories. The island was discovered and named by the British explorer William Smith in 1819, who named it after the then King, George III. It is approximately long and wide with a land area of. Over 90% of the island's surface is permanently glaciated. In 1821, 11 men of the sealing vessel Lord Melville survived the winter on the island, the first men to do so in Antarctica.
Human habitation of King George Island is limited to research stations belonging to Argentina, Brazil, Chile, China, South Korea, Peru, Poland, Russia, Uruguay, and the United States. Most of these stations are permanently staffed, carrying out research into areas as diverse as biology, ecology, geology, and palaeontology. Base Presidente Eduardo Frei Montalva, the Chilean Station on the Fildes Peninsula, is operated as a permanent village with an airstrip, cafeterias for personnel of its several agencies there, a bank, a post office and comfortable ranch-style family homes with children. Chile regards all of the Antarctic Peninsula and South Shetland Islands as part of that country's territory; however, the terms of the Antarctic Treaty allow Chile to colonize the Fildes Peninsula without overtly pursuing its territorial claims. The Chinese Great Wall base features an indoor multipurpose room which serves as a full-size basketball court. In 2004, a Russian Orthodox church, Trinity Church, was opened on the island near Russia's Bellingshausen Station. The church, one of the southernmost in the world and one of the few permanent structures in Antarctica, is permanently manned by a priest. In October 2013, American heavy metal band Metallica announced that it would perform a concert sponsored by The Coca-Cola Company at Carlini Station heliport. The concert took place on December 8, 2013. The first attempted murder in Antarctica occurred on the island in 2018 at Russia's Bellingshausen Station. A small amount of specialised tourist activity also takes place during summer, including an annual marathon, known as the Antarctic marathon. The Fildes Peninsula long, forms the SW extremity of the island. It was named from association with nearby Fildes Strait by the UK-APC in 1960. Point Thomas lighthouse at Arctowski Station is the most southerly lighthouse of the world. NOAA runs Lenie Base, a seasonal research station for penguin studies on Admiralty Bay. This small station, dubbed Copacabana, operates in the Antarctic summer only, but is used as a survival hut in the winter.
Climate
The Antarctic Peninsula and its nearby islands are considered to have the mildest living conditions in Antarctica. The island's climate is strongly influenced by the surrounding ocean. Under the Köppen system, it is one of the few locations in Antarctica classified as a tundra climate rather than an ice cap climate. Variation in temperatures are small with the coldest month, July averaging and in the warmest month. With only 591.3 hours of sunshine per year, the weather is often unsettled and cloudy throughout the year with precipitation in the form of snow, rain and drizzle occurring often. On average, 729 mm of precipitation falls per year.
