Fuerza de San Pedro or Fort San Pedro is a military defence structure, built by Spanish and indigenous Cebuano labourers under the command of Spanish conquistador, Miguel López de Legazpi and the Spanish Government in Cebu. It is located in the area now called Plaza Indepedencia, in the Pier Area of Cebu City, Philippines.
The smallest, oldest triangular bastion fort in the country was built in 1738 to repel Muslim raiders. In turn, it served as a stronghold for Filipino revolutionaries near the end of the 19th century. This served as the nucleus of the first Spanish settlement in the Philippines.
The fort is triangular in shape, with two sides facing the sea and the third side fronting the land. The two sides facing the sea were defended with artillery and the front with a strong palisade made of wood. The three bastions were named La Concepción (SW); Ignacio de Loyola (SE), and San Miguel (NE). It has a total inside area of 2,025 square metres (21,800 sq ft). The walls are 20 feet (6.1 m) high, 8 feet (2.4 m) thick and the towers are 30 feet (9.1 m) high from the ground level. The circumference is 1,248 feet (380 m). The sides are of unequal lengths and the one fronting the city is where one may find entry into the Fort. Fourteen cannons were mounted in their emplacements most of which are still there today. Work first started on May 8, 1565 with Miguel Lopéz de Legazpi breaking ground.
