It was first used as a fort for the Spanish army to advance and control the territory, and it was officially baptised on Christmas Eve of December 1603 with the name of Nacimiento de Nuestro Señor (Nativity of Our Lord). Destroyed in the later risings of the Mapuche and repaired in 1665, 1724 and for the last time in 1739, it was transferred with its inhabitants in 1749 to the site of the current town.
For a long time it was considered the last frontier of Chile, but after the arrival of foreign investors and developers it became a very prosperous city. The Palacio Gleisner is testament to that early prosperity.
Among the rivers that surround the city include the Bío Bío and the Vergara rivers. Industrial practices of lumber companies such as Mininco, Inforsa and Santa Fé (among others) have caused contaminants to pollute the waters of the Vergara River, which was the life source of local agricultural cultivation.
