Fort San Pedro was built by Spanish and Cebuano laborers as a military defense structure. The fort’s name was taken from Miguel Lopez de Legazpi’s flagship “San Pedro” in which he sailed the Pacific Ocean.
Fort San Pedro is triangle in shape with one side fronting the land and the other two sides facing the sea. The two sides facing the sea were defended with artillery and the front with a strong palisade made of wood. On each corner of the Fort are three towers that served as bastions.
These are La Concepcion at the southwest, Ignacio de Loyola at the southeast, and San Miguel at the North. As originally intended, these bastions are actually viewing decks.
