Cabo de Hornos (Cape Horn) is a Chilean commune located in the south of Tierra del Fuego archipelago, in Antártica Province, Magallanes Region. The municipality of Cabo de Hornos, located in the town of Puerto Williams, also administers the Antártica commune. It is named for Cabo de Hornos, or "Cape Horn", the southern tip of South America.
Puerto Williams (Spanish: [ˈpweɾto ˈ(ɣ)wiljams]; Spanish for "Port Williams") is a city, port and naval base on Navarino Island in Chile. 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, is the main city inside the Cape Horn Biosphere Reserve, 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.
The port attracts tourists going to Cape Horn or Antarctica; its tourism industry developed around the concept of "the world's southernmost city". Based on some definitions of what constitutes a city, Puerto Williams could in fact be the southernmost city in the world. However, others dispute this because of the small settlement size and population in favor of Ushuaia or Punta Arenas. Chilean and Argentine media, a bilateral agreement between Chile and Argentina, and the Puerto Williams administration identify it as the southernmost city in the world.
Antártica Chilena Province (Spanish: Provincia Antártica Chilena) is the southernmost of the four provinces in Chile's southernmost region, Magallanes and Antártica Chilena Region (XII). The capital is Puerto Williams. The province comprises the extreme southern part of Isla Grande de Tierra del Fuego (south of the Cordillera Darwin), the islands south and west of Isla Grande (Diego Ramírez Islands and its National Park, Diego Ramirez Islands & Drake Passage National Park), and Chile's claims in Antarctica. The province is administratively divided into two communes (comunas): Cabo de Hornos, located at the southern tip of South America, and Antártica, a wedge-shaped claim of Antarctica, which is not internationally recognized. Its total area of 1,265,853.7 km (488,749 sq mi) makes it almost twice as large as all other provinces of Chile combined.
Antártica is a Chilean commune in Antártica Chilena Province, Magallanes y la Antártica Chilena Region, which covers all the Chilean Antarctic Territory (the territory in Antarctica claimed by Chile). It ranges from 53°W to 90°W and from the South Pole to 60°S, overlapping the Argentine and British Antarctic claims, and is the largest and least populated commune in Chile, being over 25 times the size of the next largest commune, Natales. It is administered by the Cabo de Hornos municipality in the South American mainland.
Antártica was created on 11 July 1961, and was dependent on the Magallanes Province until 1975, when the Antártica Chilena Province was created, making it dependent administratively on Puerto Williams, the province capital.
Picton, Lennox and Nueva (Spanish: Islas Picton, Nueva y Lennox) form a group of three islands (and their islets) 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 km (Lennox), 105.4 km (Picton), 120.0 km (Nueva).
Close to the islands are the islets of Snipe, Augustus, Becasses, Luff, Jorge, Hermanos, Solitario, Gardiner, Terhalten, Sesambre and others.

It is 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.
