Gattaran
Gattaran lies along the Cagayan River in northern Luzon, between the inland valley and the river's mouth. Dominican missionaries established a mission here in 1623. Its church of Saint Catherine was later built in red brick and completed in 1739. Nearby Nassiping, an older mission near the meeting of the Chico and Cagayan rivers, also had a stone church. These river settlements formed part of the network through which missionaries and colonial officials worked in the valley.
