Concepción is a city and commune in central Chile, and the geographical and demographic core of the Greater Concepción metropolitan area, one of the three major conurbations in the country. It has a significant impact on domestic trade being part of the most heavily industrialized region in the country. It is the seat of the Concepción Province and capital of the Bío Bío Region. It sits about 500 km south of the nation's capital, Santiago.
The city was first settled in the Bay of Concepción, in the zone that would later become the commune of Penco, now part of the Concepción conurbation. The city's demonym, «penquista», comes from the place of its original foundation. The city center and historic district is located in the Valle de la Mocha, where it relocated after serious damages left by an earthquake.
The origin of Concepción dates back to 1550, when it was founded by Pedro de Valdivia as part of the Spanish Empire, under the name of Concepción de María Purísima del Nuevo Extremo, and was the capital of the Kingdom of Chile between 1565 and 1573, holding the position of military and political center of the kingdom for the rest of the Chilean colonial period.
