Mission San Borja Hot Springs
Mission San Borja Hot Springs are located on the grounds of the historical Misión San Francisco Borja near the town of Rosarito in Baja California, Mexico.
History
In 1752, the Jesuit missionary, Georg Retz arrived at the springs and ordered the building of a visita or subordinate mission for Misión Santa Gertrudis, at a San Borja Adác site. In 1758, Retz sent a group to confirm the hot water springs and cold springs at San Borja Adác.The hot mineral springs are located on the site of the Spanish Misión San Francisco Borja founded in 1762 by the Jesuit priest and explorer Wenceslaus Linck who worked with the local indigenous Northern Cochimí people who had been Christianized by Retz.
The rock-lined soaking pool at the source was built in the early 1880s by the missionaries.
