Provinces of Chile in the context of "Malleco Province"

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.

Antofagasta Province (Spanish: Provincia de Antofagasta) is one of three provinces in the northern Chilean region of Antofagasta (II). The capital is the port city of Antofagasta. Located within the Atacama Desert, it borders the El Loa and Tocopilla provinces to the north, the Pacific Ocean to the West and the Atacama Region to the south.

Chile is divided into 16 regions (Spanish: regiones, singular región), which are the country's first-level administrative division. Each region is headed by a directly elected regional governor (gobernador regional) and a regional board (consejo regional).

The regions are divided into provinces (the second-level administrative division), each headed by a governor (gobernador) appointed by the President. There are 56 provinces in total. Provinces are divided into communes (the third and lowest level administrative division), which are governed by municipal councils.

The Magallanes Region (locally [maɣaˈʝanes]), officially the Magallanes y la Antártica Chilena Region (Spanish: Región de Magallanes y de la Antártica Chilena) or Magallanes and the Chilean Antarctica Region in English, is one of Chile's 16 first order administrative divisions. It is the southernmost, largest, and second least populated region of Chile. It comprises four provinces: Última Esperanza, Magallanes, Tierra del Fuego, and Antártica Chilena. The region takes its name from the Strait of Magellan which runs through it, which was in turn named after Ferdinand Magellan, the leader of the European expedition that discovered it.

Magallanes's geographical features include Torres del Paine, Cape Horn, Tierra del Fuego island, and the Strait of Magellan. It also includes the Antarctic territory claimed by Chile. Despite its large area, much of the land in the region is rugged or closed off for sheep farming, and is unsuitable for settlement. 80% of the population lives in the capital Punta Arenas, a major market city and one of the main hubs for Antarctic exploration.

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.

The administrative division or territorial organization of Chile exemplifies characteristics of a unitary state. State administration is functionally and geographically decentralized, as appropriate for each authority in accordance with the law.

For the interior government and administration within the State, the territory of the republic has been divided into 16 regions (regiones), 56 provinces (provincias) and 346 communes (comunas) since the 1970s process of reform, made at the request of the National Commission on Administrative Reform (Comisión Nacional de la Reforma Administrativa or CONARA). State agencies exist to promote the strengthening of its regionalization, equitable development and solidarity between regions, provinces and communes within the nation.

Chiloé Province (Spanish: Provincia de Chiloé) is one of the four provinces in the southern Chilean region of Los Lagos (X). It consists of all of Chiloé Archipelago (including Chiloé Island) with the exception of the Desertores Islands. The province spans a surface area of 9,181.6 km (3,545 sq mi). Its capital is Castro, and the seat of the Roman Catholic bishopric is Ancud.
