Santiago, also Santiago de Chile is the capital and largest city of Chile and the center of its largest conurbation. It is located in the country’s central valley, at an elevation of 520 m above mean sea level.Founded in 1541, Santiago has been the capital city since colonial times. The city has a downtown core of 19th century neoclassical architecture and winding side-streets, dotted by art deco, neo-gothic, and other styles. Santiago’s cityscape is shaped by several stand-alone hills and the fast-flowing Mapocho River, lined by parks such as Parque Forestal. Mountains of the Andes chain can be seen from most points in the city. These mountains contribute to a considerable smog problem, particularly during winter. The city outskirts are surrounded by vineyards, and Santiago is within a few hours of both the mountains and the Pacific Ocean.
