Fuerte de 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 the city. 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.
