Santiago

Santiago ( SAN-tee-AH-goh, US also SAHN-; Spanish: [sanˈtjaɣo]), also known as Santiago de Chile (Spanish: [sanˈtjaɣo ðe ˈtʃile] ), is the capital and largest city of Chile and one of the largest cities in the Americas. Located in the Chilean Central Valley within the Santiago Basin, between the Andes to the east and the Chilean Coastal Range to the west, it anchors the Santiago Metropolitan Region and its conurbation of Greater Santiago, which comprises more than forty communes and concentrates over a third of the national population and around 45% of Chile's GDP. Most of the city lies between 500 and 650 meters (1,640 and 2,130 ft) above sea level, with recent urban growth extending into the Andean foothills.

The basin that Santiago occupies has been inhabited since at least the 10th millennium BC, with early agricultural villages established along the Mapocho River and later incorporated into the Inca sphere of influence. During the Spanish invasion of the Americas, conquistador Pedro de Valdivia founded the colonial city of Santiago del Nuevo Extremo on 12 February 1541, laying out a grid plan around the Plaza Mayor (now Plaza de Armas). Despite early food shortages, Indigenous attacks, floods, and devastating earthquakes—notably in 1647—the city consolidated as the capital of the Captaincy General of Chile. Santiago remained the political center during the Chilean War of Independence, beginning with the First Government Junta in 1810 and culminating in patriot victory at the Battle of Maipú in 1818, and subsequently expanded through 19th-century railway construction, state-building projects, and the creation of major educational and cultural institutions.

The city today is the political and administrative heart of Chile: it houses the presidential palace and the main organs of the executive and judiciary, while the National Congress meets primarily in nearby Valparaíso. Economically, Santiago is the country's principal industrial, commercial, and financial hub and a regional center for services, hosting the headquarters of major Chilean companies, regional offices of international organizations such as the Economic Commission for Latin America and the Caribbean (ECLAC), and several of the nation's leading universities and research institutes. Urban growth has been marked by the emergence of high-rise business districts such as Sanhattan, dominated by Gran Torre Santiago, the tallest building in South America and the second tallest building in Latin America (behind Mexico's T.Op Torre 1).

Santiago's urban landscape combines a 19th-century neoclassical core and surviving colonial churches with extensive modern residential districts, standalone hills such as Cerro Santa Lucía and Cerro San Cristóbal, and parklands along the Mapocho River, including Parque Forestal, Bicentennial Park, and Santiago Metropolitan Park.
