The island of Mindanao has always been a problem for the Spanish colonial governement. Although it was able to establish towns and build churches, it’s authority has always been challenged not only by the Muslims who raided its pueblos for the slave markets in Batavia and then in Sulu, but also by indigenous peoples who refused to be subjugated.
Thus the building of forts, either made of wood or in some cases, of stone were built around the island of which only a small portion are left: Fort Pilar in Zamboanga City, Fuerza de la Nuestra Señora de la Concepción y Triunfo in Ozamiz City, some watchtowers in Camiguin and fort ruins in Pikit and Lanao del Norte.
Fort Almonte in Lianga East, Bacolod, Lanao del Norte was an attempt by the Spaniards to finally have Mindanao under its control for its economic importance, as areas for agricultural colonies. It was built at the twilight of Spanish colonization in 1892 using stones from the sea and served as a municipal and coastal defense.
Located at a hill overlooking the main road, it’s a quadrilateral fort with a bastion but its layout is difficult to ascertain because of its ruined state. It was supposedly used as Japanese garrison during World War II. A printed material at the school mentions that old people in the area said that there is a tunnel underneath the fort leading to the riverbank but has been covered already.
