The history of Algarrobo dates back to pre-Hispanic times, when the area was inhabited by the Chango indigenous people, who mainly dedicated themselves to fishing and shellfish gathering.
During the colonial era, the territory was occupied by the Spanish and haciendas dedicated to agriculture and livestock were established in the area.
In the 19th century, with the rise of saltpeter mining, Algarrobo became an important export port for this product.
The fishing industry and wine production also developed. During the 20th century, the city was consolidated as a summer tourist destination, thanks to its beaches and natural attractions.
Currently, Algarrobo continues to be an important tourist destination in central Chile, with a wide range of recreational and cultural activities for its visitors.
