San Agustín Church is a Roman Catholic church under the auspices of The Order of St. Augustine, located inside the historic walled city of Intramuros in Manila. Completed by 1607, it is the oldest church currently standing in the Philippines. No other surviving building in the Philippines has been claimed to pre-date San Agustin Church.
In 1993, San Agustin Church was one of four Philippine churches constructed during during the Spanish colonial period designated by the UNESCO as a World Heritage Site, under the classification "Baroque Churches of the Philippines". It had been named a National Historical Landmark by the Philippine government in 1976.
San Agustín Church measures 67.15 meters long and 24.93 meters wide. Its elliptical foundation has allowed it to withstand the numerous earthquakes that have destroyed many other Manila churches. It is said that the design was derived from Augustinian churches built in Mexico, and is almost an exact copy of Puebla Cathedral in Puebla, Mexico. The facade is unassuming and even criticized as "lacking grace and charm", but it has notable baroque touches, especially the ornate carvings on its wooden doors.[5] The church courtyard is graced by several granite sculptures of lions, which had been gifted by Chinese converts to Catholicism.
