A Spanish expeditionary force sent from Vigan by the military officer and navigator, Captain Juan de Salcedo was shipwrecked along the town's coast in 1576. When they were being rescued by the natives, the Spaniards asked the natives what was the name of their place. The resident's leader replied in an Ilocano dialect by asking the Spaniards "Nalbakan?" (Are you shipwrecked?). The Spaniards thought this to be the answer to their question, and from then on the place was referred to as Narvacan.

Salcedo befriended the small tribe of indigenous valley peoples that resided in the area while Spanish families established a township in 1576. As part of the modern township, a Roman Catholic parish was established by the Augustinian religious order on 25 April 1587. The Narvacan parish would become one of the first Roman Catholic parishes in present-day Ilocos Sur.

Narvacan was organized under the traditions of the royal government of Spain. The Habsburg royal family served as the heads of state which in turn appointed Santiago de Vera as President of the Royal Audiencia – governor over the region in which Narvacan was situated. In 1589, Governor Vera appointed Nicolas de Figueroa as the first Encomendero de Narvacan – principal administrator of the town and its neighbors in the encomienda system. His role eventually evolved into the office of alcalde
