One of the artistic and religious landmarks of the fishing town, the church was built in the 18th century. Located in a privileged setting overlooking the Bay of Biscay, it has a rectangular nave and flat apse. The historicist bell tower was built later, in the 19th century, at the west end, as were the chamber adjoining the north wall and the porch resting on Tuscan columns that surrounds the church.
The materials used in its construction are masonry in the walls and sandstone ashlar in the corners, pillars and buttresses, along with a red tile roof.
Inside, the nave is divided by transversal arches into four sections covered with groin vaulting like the chancel. There is a wooden choir at the west end.
The richness of the 18th-century altarpieces preserved in the nave, three on each side, is worth highlighting, as is the chapel which was paid for by the Merchants Guild.
