The Our Lady of Atocha Parish Church in Alicia, Isabela stands along the Maharlika Highway in Barangay Magsaysay. Established by Dominican missionaries in the 18th century, the church reflects the early spread of Catholicism in the region. The present structure was completed and inaugurated in 1849.

The church is built mainly of brick, a common material used in many churches in the valley. Its façade follows a simple Spanish Castilian style, with a symmetrical layout and minimal ornamentation. The overall design is straightforward, with its aged bricks giving it a distinct historical character. Inside, the church maintains a modest and functional layout. The interior is simple, allowing focus on the altar and religious activities.

The church is dedicated to Our Lady of Atocha, a Marian title that originated in Spain, particularly in Madrid. The devotion is associated with a small image of the Virgin Mary depicted as a Black Madonna, often shown holding the Child Jesus. The Child is traditionally portrayed carrying a pilgrim’s staff, a gourd, or a basket, symbolizing assistance to travelers and those in need. Historically, Our Lady of Atocha became known as a protector of prisoners, the poor, and pilgrims, especially during times of conflict in Spain. This devotion was later brought to the Philippines during the Spanish colonial period and became established in several communities, including Alicia.

In 2019, the church was declared an Important Cultural Property by the National Museum of the Philippines, recognizing its historical and cultural value. It has also been identified as a National Religious Tourist Attraction.
