Santiago was founded on Feb. 12, 1541, by the Spanish conquistador Pedro de Valdivia. After the independence of Chile was proclaimed in 1818, it became the country’s capital. Santiago has been Chile’s industrial center since the early 20th century and, throughout this period, has been the scene of the Chilean proletariat’s most significant anti-imperialist demonstrations, especially in the 1930’s and in 1950, 1954–55, and 1966. After S. Allende’s government of Popular Unity took power in November 1970, Santiago witnessed bitter class fighting between the opposition and the supporters of Popular Unity. On Sept. 11, 1973, reactionary military leaders overthrew the government of Popular Unity; Allende was killed during the storming of La Moneda, the presidential palace.
In Santiago, which was given a grid plan in the mid-16th century, the houses are uniformly low and wide and enclose small courtyards. The Plaza de Armas occupies the city center; it is flanked by buildings dating from the colonial period and done mostly in a baroque style: the Cathedral (1541–1619, completed 1780; architect J. Toesca) and the city hall (second half of the 18th century; architects Toesca and M. de Jaraquemada). Outstanding examples of colonial architecture are the Church of San Francisco (1618) and the Mint (La Moneda, later the presidential palace; begun 1782, architect Toesca; bombed during the 1973 coup). Since the late 19th century the streets of Santiago have been paved and landscaped, and various parks have been laid out. Many buildings are done in the neoclassical, neo-Gothic, or art nouveau style. In the central, western, and southwestern sections of the city, modern administrative, business, and apartment buildings rise eight to 12 stories high; there are also many mansions.
