Also known as Saint Augustine Church, the religious sanctum is famous for its distinct architecture: it was built using 24 huge buttresses at the side and the back, and is a prime example of a Spanish colonial baroque architecture to fortify the church against earthquakes. The walls of the Paoay Church are made out of coral stones, while its three-storey bell tower stand proud after it saw the turn of history when it was used as an observation post of Filipino revolutionaries and guerrillas.
Paoay Church was declared as a National Cultural Treasure in 1973 through Presidential Decree No. 260. It was also deemed a UNESCO World Heritage Site on December 11, 1993.
