The church is dedicated to the Italian saint Catherine of Siena. The Dominicans constructed the first church in 1596. It is under the jurisdiction of the Diocese of Balanga.

The Dominicans in 1596 directed the spirituality of Samal. Attacked by Dutch invaders in April 1647, the local garrison of Pampanga under Alejo Aguas ousted the Dutch forces. Rev. Jeromino Belen, O.P. rebuilt the ruined church and the convent. In 1896 the Katipuneros burned the church and convent which were rebuilt by Rev. Justo Quesada in 1903.

The National Historical Commission of the Philippines declared the church as a national historical landmark in 1939.
