Whenever the subject of Manila’s fortifications is discussed, automatically Fort Santiago is the one that first comes to mind. After all, it is the most well-known city fortification that has not only managed to survive the centuries, but also rose to become a popular tourist destination. But hidden south of the city lies another historic fortification, smaller and understandably overlooked these days considering its current location. This is the Fort San Antonio Abad, Manila’s hidden fort that lies between the imposing Bangko Sentral ng Pilipinas buildings and the Metropolitan Museum of Manila.
