The San Agustin Church is a historic site in Intramuros, Manila. Also known as the Church of the Immaculate Conception of San Agustin, it is considered the oldest church in the Philippines, recognized by the NCCA and a UNESCO Heritage Site. Like the other old churches, it faced several natural disasters, like earthquakes, and was burned several times. The very first structure was built in 1571, made of nipa and bamboo, but was destroyed by fire during the invasion of Limahong, a Chinese pirate, in 1574. In the same spot, a new structure was built and was made of wood. In 1586, a new structure made of adobe stone was constructed, led by the Augustinians.
