The Commune of Santiago is the central commune of the Santiago Province, located at the center of the Santiago Metropolitan Region in Chile's Central Zone. Locally, Santiago is usually abbreviated Stgo. It is also called as "Santiago Centro" (Central Santiago) in order to differentiate it from Greater Santiago, a larger entity which includes Santiago Commune along with other 36 communes.
The city of Santiago was founded on February 12, 1541 as "Santiago de la Nueva Extremadura" by Pedro de Valdivia. It is officially the provincial, regional and national capital. It encompasses the oldest part of the city —that enclosed by old rail lines—, including downtown, and houses all major government infrastructure, including the government palace La Moneda.
