Fort de la Encarnación on the Repocura River was built in 1666 by the Royal Governor of Chile Francisco de Meneses Brito. It was destroyed during a Mapuche rising in 1694 and rebuilt by Tomás Marín de Poveda with a nearby mission in December of the same year. These were destroyed in the 1723 Mapuche rising. Rebuilt again as Fort Repucura by Governor Antonio de Guill y Gonzaga in 1764, it was destroyed for the last time in the Mapuche Uprising of 1766.
