The St. Rose of Lima Parish Church, commonly known as Gamu Church, is one of the long-established Catholic churches in Isabela, located in the municipality of Gamu. Its origins date back to the Spanish colonial period, when Dominican missionaries organized missions across the Cagayan Valley. The church was constructed around 1750 by Martin Fernández, a priest who also laid out the town planning of Gamu, making it one of the early organized settlements in the area.
