The image of Our Lady, which was then called Our Lady of the Holy Rosary, was brought to the Itawes region from its church in Lal-lo, then the seat of the Diocese of Nueva Segovia, in 1620 to settle the conflict between the Christians and the Itawes tribe.

Her coming brought peace and in no time at all, her small chapel in Piat, where the present church now stands, became a place of worship for both Catholics and the Itawes.
