Fuerza de San Pedro is a military defense 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. 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 sq. meters. 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 date of construction of the stone fort is uncertain, although there are claims that a Jesuit Antonio Campioni built a stone fort in 1630, and the gate of fort bears the date 1738 together with the arms of Castile and Leon. It is certain, however, that the fort underwent major renovations in the late 1800s as part of a building program to improve Cebu City.

At present, it is under the care and administration of the City of Cebu as historical park. The land on which it is situated is, however, owned by the Department of Environment and Natural Resources. These days, part of the fort is a museum. Inside the fort houses the legacies of the Spanish Government, including well-preserved Spanish artifacts such as Spanish documents, paintings and sculpture. A large statue of Legazpi and Antonio Pigafetta may be seen outside the fort walls.
