The order of the Augustinians, Augustinian Province of the Most Holy Name of Jesus of the Philippines, built many churches all over the Philippines. These magnificent structures can still be found throughout the Philippine Islands.The Paoay Church in Ilocos Norte is one of the most prominent types of these churches. This unique specimen of Filipino architecture called Filipino Baroque from the Spanish era has been included in the World Heritage Sites List of the UNESCO. The church was built by the Augustinian friars from 1694 until 1710. It shows the earthquake-proof baroque style architecture. The bell tower served as an observation post in 1896 for the Katipuneros during the Philippine revolution against the Spaniards, and again by the Filipino guerillas during the Japanese occupation in World War II.
