Puerto Williams is a city, port and naval base on Navarino Island in Chile, and is also the southernmost populated settlement in the world. It faces the Beagle Channel. It is the capital of the Chilean Antarctic Province, one of four provinces in the Magellan and Chilean Antarctica Region, and administers the communes of Chilean Antarctic Territory and Cabo de Hornos. It has a population of 2,874, including both naval personnel and civilians. Puerto Williams claims the title of world's southernmost city. The settlement was founded in 1953, and was first named Puerto Luisa. The town was later named after John Williams Wilson, a British man who founded Fuerte Bulnes, the first settlement in the Strait of Magellan. It has served primarily as a naval base for Chile. The Chilean Navy runs the Guardiamarina Zañartu Airport and hospital, as well as nearby meteorological stations. Since the late 20th century, the number of navy personnel has decreased in Puerto Williams and the civilian population has increased. In that period, tourism and support of scientific research have contributed to an increase in economic activity.
Beagle Channel is a strait in the Tierra del Fuego Archipelago, on the extreme southern tip of South America between Chile and Argentina. The channel separates the larger main island of Isla Grande de Tierra del Fuego from various smaller islands including the islands of Picton, Lennox and Nueva; Navarino; Hoste; Londonderry; and Stewart. The channel's eastern area forms part of the border between Chile and Argentina and the western area is entirely within Chile.
Picton, Lennox and Nueva form a group of three islands at the extreme southern tip of South America, in the Chilean commune of Cabo de Hornos in Antártica Chilena Province, Magallanes and Antártica Chilena Region. Located in the Tierra del Fuego archipelago, they lie east of Navarino Island and are separated from the Argentine part of Isla Grande in the north by the Beagle Channel. They have an area of 170.4 km2 (Lennox), 105.4 km2 (Picton), 120.0 km2 (Nueva).
The Beagle conflict was a border dispute between Chile and Argentina over the possession of Picton, Lennox and Nueva islands and the scope of the maritime jurisdiction associated with those islands that brought the countries to the brink of war in 1978.
Navarino Island is a Chilean island located between Isla Grande de Tierra del Fuego, to the north, and Cape Horn, to the south. The island forms part of the Commune of Cabo de Hornos, the southernmost commune in Chile and in the world, belonging to Antártica Chilena Province in the XII Region of Magallanes and Chilean Antarctica. Its population is concentrated primarily in the communal capital, Puerto Williams, and in small settlements like Puerto Navarino, Río Guanaco and Puerto Toro. The highest point of the island is Pico Navarino at 1,195 m (3,921 ft). The island is a popular destination for fly-fishers.
Isaac Francisco Rojas Madariaga was an Argentine Admiral of the Navy and de facto Vice President of Argentina. He joined the Argentine Navy and had an unremarkable career until the 1946 election of Juan Perón.
International relations between the Republic of Chile and the Argentine Republic have existed for decades. The border between the two countries is the world's third-longest international border, which is 5,300 km (3,300 mi) long and runs from north to south along the Andes mountains. Although both countries gained their independence during the South American wars of liberation, during much of the 19th and the 20th century, relations between the countries were chilly as a result of disputes over the border in Patagonia. Despite this, Chile and Argentina have never been engaged in a war with each other. In recent years, relations have improved. Argentina and Chile have followed quite different economic policies. Chile has signed free trade agreements with countries such as China, the United States, Canada, South Korea, as well as European Union, and it's a member of the APEC. Argentina belongs to the Mercosur regional free trade area. In April 2018, both countries suspended their membership from the UNASUR.
Cabo San Pío at 55°3′S66°31′W, the southernmost tip of mainland Isla Grande de Tierra del Fuego as well as of Argentina, except for the small islet Islote Blanco that lies about 1.5 kilometres (0.93 mi) off the coast in SW direction.
The region of the Beagle Channel, explored by Robert FitzRoy in the 1830s, was one of the last to be colonized by Chile and Argentina. The cold weather, the long distances from other inhabited regions, and the shortage of transport and subsistence, kept it far from the governmental task.
On 22 July 1971 Salvador Allende and Alejandro Lanusse, the Presidents of Chile and Argentina, signed an arbitration agreement. This agreement related to their dispute over the territorial and maritime boundaries between them, and in particular the title to the Picton, Nueva and Lennox islands near the extreme end of the American continent, which was submitted to binding arbitration under the auspices of the United Kingdom government.
Operación Soberanía was a planned Argentine military invasion of Chile due to the Beagle conflict. The invasion was initiated on 22 December 1978 but was halted after a few hours and Argentine forces retreated from the conflict zone without a fight. Whether the Argentine infantry actually crossed the border into Chile has not been established. Argentine sources insist that they crossed the border.
The direct negotiations between Chile and Argentina about the islands and maritime rights in Beagle conflict began after the Queen Elizabeth II of the United Kingdom announced on 2 May 1977 the judgement of the Beagle Channel Arbitration to the governments of both countries. The court ruled that the islands and all adjacent formations belonged to Chile. The direct negotiations finished with the Act of Montevideo on 9 January 1979, where both countries accept the papal mediation after Argentina's call off of the Operation Soberanía. This was the most dangerous phase of the Beagle Conflict and there was a real possibility of open warfare.
The papal mediation in the Beagle conflict followed the failure of negotiations between Chile and Argentina, when, on 22 December 1978, the Argentinian Junta started Operation Soberanía, to invade Cape Horn and islands awarded to Chile by the Beagle Channel Arbitration. Soon after the event, Pope John Paul II offered to mediate and sent his personal envoy, Cardinal Antonio Samoré, to Buenos Aires. Argentina, in acceptance of the authority of the Pope over the overwhelmingly Catholic Argentine population, called off the military operation and accepted the mediation. On 9 January 1979, Chile and Argentina signed the Act of Montevideo formally requesting mediation by the Vatican and renouncing the use of force.
The Treaty of Peace and Friendship of 1984 between Chile and Argentina was signed into agreement at the Vatican on 29 November 1984.
The islands of Chile encompass the various islands that the government of Chile has sovereignty over. By far the majority of these are the islands in the south of the country. Chile has one of the world's longest coastlines, and one of the most dangerous for boats; it is more than 4,000 kilometres (2,500 mi) long and has at least 43,471 islands.
The Micalvi was an auxiliary vessel of the Chilean Navy.
The Quidora was one of four torpedo boats built in Spain for the Chilean Navy since 1962, based originally in the Jaguar-class fast attack craft FPB-36 design of the German Lürssen Werft. Her sister ship Fresia PTF-81 is now a museum ship in Punta Arenas.
