Penco
city and commune of Chile
Penco (Mapudungun: See (Pen), Water (Ko)), is a Chilean city and commune in Concepción Province, Bío Bío Region on the Bay of Concepción. Founded as the city of Concepción del Nuevo Extremo (lit. 'Beginning of the New Extreme') on February 12, 1550, by Pedro de Valdivia, it is the third oldest city in Chile, after capital Santiago founded first in 1541 and La Serena second in 1544.
As there may be confusion between the demonyms of the inhabitants of Concepción and Penco, due to the previous location of Concepción, inhabitants of that city are called penquistas while inhabitants of Penco are known as pencones.
The commune is since 2016 the site of a project to mine rare-earth elements by Aclara Resources, a publicly traded company with a 55.9% and 10.1% ownership of Hochschild Mining and CAP respectively.
History
In previous centuries, in the current location of Penco, was the first location where the city of Concepción was established, which is now the capital of the Bíobío Region. It was destroyed by Lautaro in 1554, and rebuilt and destroyed again by Lautaro in 1555.
It was reestablished in 1557 during the governorship of marquess García Hurtado de Mendoza when he landed there and built a fort on the Alto de Pinto. The city was reestablished January 6, 1558, by capitán Jerónimo de Villegas.
It became the headquarters of the military forces engaged against the native Mapuche in Araucanía over the next two centuries, growing to a population of 10,000 despite suffering a siege in 1564 and other attacks by Mapuche tribals.
In 1603 the last bishop of the suppressed Diocese of La Imperial was transferred there as first bishop of the successor see Roman Catholic Archdiocese of Concepción.
This brief starts where responsible research should: with the source description of “Penco” as city and commune of Chile. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the places & architecture register because the source frames it as city and commune of Chile. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Mar 30, 2026. The linked authority identifier is Q51093. VIAF identifies the subject as 130495218. The Library of Congress control number is no97041577. Authority coordinates are -36.739, -72.994. 4 of 5 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1550, 1541, 1544 and 2016.
Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
