History and Governance
European influence in the region began in 1542 shortly after the founding of Santiago. Initially, the Santiago cabildo (municipal council) supervised the entire territory, though its reach diminished as La Serena and Concepción established their own councils. While the Santiago Province was created in 1826, the formal Metropolitan Region was not established until 1980.
Today, the region is governed by a popularly elected governor, currently Claudio Orrego. Administrative oversight is further supported by the Presidential Delegate, a role held by Germán Codina since March 11, 2026.
Geography and Natural Environment
The region is situated in the Intermediate Depression, a fertile valley located between the Chilean Coast Range and the Andes Mountains. The landscape is characterized by level prairies and "island hills," such as Santa Lucía—an ancient extinct volcano—as well as Blanco and Renca.
The skyline is dominated by Cerro San Cristóbal (880 m), while the eastern border is marked by the towering Andes, including the Tupungato stratovolcano, which reaches 6,570 m on the Argentine border. The region's hydrology is centered on the Maipo River basin, fed by the Mapocho, Yeso, and Colorado rivers.
The environment is also home to the endangered Chilean Wine Palm (Jubaea chilensis), an iconic species whose habitat has shrunk due to human expansion. Additionally, the region is rich in mineral resources, featuring copper deposits such as the Los Bronces mine in the high Andes and the now-closed Lo Aguirre mine to the west.
Climate
The region experiences a temperate Mediterranean cold climate, specifically a continental variation. The Cordillera de la Costa (Coast Range) acts as a barrier that reduces marine influence, resulting in lower precipitation than coastal cities; Santiago averages 360 mm annually compared to Valparaíso's 460 mm.
Winters are cold with frequent frosts and precipitation that falls as snow at elevations above 900 m. Summers are typically hot and dry. The median annual temperature is 13.5 °C, though rural areas can drop as low as −10 °C during July and August.
Demographics and Economy
The region is overwhelmingly urban, with 96.2% of its 7,400,741 residents living in cities. The population is slightly skewed toward females (51.6%) and shows a younger demographic profile than the national average, with 17.3% of the population under the age of 15.
Economically, the region is the powerhouse of Chile. Its primary industries include financial services, retail, manufacturing, and general services. The capital city of Santiago alone generates approximately 41.5% of the nation's gross domestic product.
Notable Landmarks
The heart of the region is the Plaza de Armas, which houses the city hall and cathedral. Political power is centered around La Moneda, the presidential palace, and the surrounding ministries. For business and international diplomacy, the Vitacura and El Golf districts feature high-rise architecture and the Latin American headquarters of various United Nations organizations. The valley also preserves 19th-century wineries, maintaining a link to the region's agricultural heritage.
