Miagao was formerly a visita (a locality served by a visiting priest) of Oton until 1580, Tigbauan until 1592, San Joaquín until 1703 and Guimbal until 1731.[1] It became an independent parish of the Augustinians in 1731 under the advocacy of Saint Thomas of Villanova.[2] With the establishment of the parish, a church and convent was built on land near the sea called Ubos. Father Fernando Camporredondo served as the town's first parish priest in 1734. When the town experienced frequent Moro invasion in 1741 and 1754, the town moved to a more secure place. From there, a new church was constructed in 1787 through forced labor under the supervision of Fray Francisco Gonzales, parish priest and Spanish gobernadorcillo Domingo Libo-on.[3] It was built on the highest point of the town to guard from invaders called Tacas. After ten years, the church was completed in 1797. It was designed with thick walls to serve as protection from invaders. It was severely damaged during the Spanish revolution in 1898 but was later rebuilt, fire in 1910, the second World War and earthquake in 1948.[3] The present day Miagao church is the third church built since its establishment in 1731.[4] To preserve the church, it underwent restoration in 1960. This was completed in 1962. It has been declared a national shrine through Presidential Decree No. 260.
