Founded in 1541 by the Spanish conquistador Pedro de Valdivia on indigenous settlements in the valley of the Mapocho River, Santiago is the capital and most populated city of Chile. This South American city is enframed by the Andes Mountains to the east and the Chilean Coast Range to the west, in addition to 26 island hills (cerros islas) scattered throughout the city. Some of these island hills have been converted into urban parks, such as Santa Lucía and San Cristóbal, while Chena, Calán, and Renca are in the process of expansion.
