Puente Alto (Spanish: 'High Bridge') is a city and commune of Chile. It is the capital of the Cordillera Province in the Santiago Metropolitan Region. Located at the south of the Great Santiago conurbation, it houses 492,603 inhabitants (city proper, 2002 census), making it the largest city in Chile (excluding conurbations or absorptions). However, the National Statistics Institute projects that Maip (also part of Great Santiago), as of 2005, has surpassed it in population. After 1883, the provience of Santiago was divided into three departments: Santiago, La Victoria and Melipilla. In 1891 the 'Autonimic Commune Law' was enacted, after which the president signed as the 'Decree of the Creation of Municipalities.' From this decree the department of La Victoria was divided into the municipalities of Peaflor, Talagante, Calera de Tango, San Jos de Maipo y Lo Caas.
