A triangular defense structure built in 1565 under the orders of Miguel López de Legazpi, first governor of the Captaincy General of the Philippines and the founder of the first Spanish settlement in Cebu. It is known as the smallest and oldest fort in the Philippines.
Over the years various enhancements were made to Fort San Pedro. For example, its stone walls, which now stand 20 feet tall and 8 feet thick, were originally made from logs when construction first began in 1565—just 11 days after Miguel López de Legazpi landed in Cebu.
