The town of Piddig is located on rolling hills and small valleys between the Guisit and Baramban rivers. The original settlers of the area were Tinggunians who cleared lands for their farms, but were later displaced by Ilocano settlers. The place was originally called Pidipid , an Ilocano term for a 'hilly place', which was later shortened to Piddig , indicating a place at the foot of a tall mountain.

The church compound in Piddig has witnessed quite a bit of history and then some. The Basi Rebels , whose leaders were from Piddig , passed through this place. Allies of the Sarrat uprising spent a fruitless day exhorting the people to join their cause. Local patriots repulsed American troops from these buildings during the Filipino-American war. On March 19, 1931 , an earthquake toppled the upper level of the belltower. American soldiers encamped here during World War II, and the Japanese retaliated by raiding and burning the town, destroying all historic records.
