San Vicente, Ilocos Sur

The municipality's name came from the name of Saint Vincent Ferrer, whose winged statue was found inside a box entangled in fishing nets. The fishermen consulted this matter to the friars in Villa Fernandina (now Vigan), who identified the person depicted by the statue. The statue was carried to the town's center, where a church was built. From then on, the town formerly known as Tuanong (sometimes called Taonan) was renamed San Vicente.

In tracing the history of San Vicente, one always has to start from Vigan. Vigan was established by the Spanish conquistador, Juan de Salcedo on June 13, 1573.

Upon Salcedo's return in 1574, he brought with them the Augustinian friars in order to proselytize Christianity among the inhabitants. After Salcedo's death on March 11, 1576, Franciscan friars replaced the Augustinians in 1579. These same friars spread up to San Vicente to convert the people to the Catholic faith.

Up until 1582, there were only about 800 residents in Vigan. In 1591, Vigan began to organize its government, which included the barrios of Tuanong, Santa Catalina de Baba, and Caoayan. There were then a population numbering about 4,000 inhabitants at this time.

Between the years 1720 and 1737, the first chapel of Barrio Tuanong was erected. Later in 1748, the Confraternity of Jesus of Nazareth was organized. In one record of the Vigan Convent archives, a funeral that took place on January 29, 1748 in the chapel of Barrio Tuanong was recorded. Two chaplains, Don Agustin de la Encarnacion and Don Pedro Geronimo de Barba, were the priests of the chapel in that year. It is believed that the chapel is the first stone building that one sees upon entering the San Vicente Central School from the main road.

On June 16, 1751, the chaplain was Don Miguel de Montanez. He was the first priest there and also in the then newly constructed chapel of San Sebastian.

Difficulties in reaching Barrio Tuanong and Barrio Santa Catalina de Baba from Vigan especially during the months of June to October were experienced due to the absence of a dike or bridge. Priests from Vigan reached these areas by means of a raft. The problem prompted the separation of these two barrios from Vigan in 1793.

In 1795, the seat of the municipality and the church in Barrio Tuanong were inaugurated, and the town became known as San Vicente. Don Pedro de Leon was the first parish priest and he was believed as the initiator of the construction of the Church of San Vicente.
