Built in 1572, the St. John the Baptist Church is the oldest church in Bulacan. Constructed under the supervision of Augustinian priest Fr. Diego Vivar-Ordoñez, the church had been witness to the Filipino’s struggle against Spanish, American and Japanese rule. Inside the church is a tunnel that, according to history, was used by priests during the Spanish regime to keep gold, religious statues, and ornate jewelry hidden from the sight of treasure hunters. Likewise, it is in this tunnel where revolutionaries and Spaniards were buried during the war.
