To detect the coming of the Moro raids, the people erected a watchtower where the sea laps at the shore nearest the present Municipal Hall. In spite of the tower, many Bagamanocnons still fell into the corsairs’ hand. When the Spaniards came, they found the place a thriving community. They converted the people into Christianity and made a settlement into a municipality under a governadorcillo. Under Spain, the town people constructed a concrete church and municipal hall of stones, limes, molasses and eggs. However, even under the Spaniard rule, Bagamanocnons did not fully submit to the Spanish dominion, although fully sold out to Christianity. During the revolution of 1898-1901, the Bagamanocnon relied their support to the Filipino Revolutionist. In fact, a bloody skirmish took place at Mapulang Labo, where then Apolonio Cueva skillfully beheaded an American Officer mounted on a horse. When the Americans reorganized the municipal government, the town was reduced to a mere town of Viga, later of Payo, until Bagamanoc became a municipality again in 1950.
