This is the town's most important monument. Dating from the eighteenth century, it consists of three naves separated by chamfered pillars with a rectangular section supporting semicircular arches.
The main chapel is roofed with a vault and the two side chapels have flat single-pitch roofs. The most important work of art in the church is the relief representing San Pablo Miki, the only remaining fragment of the original altarpiece, which can be dated to the XVIII century and is in need of urgent restoration. It was brought from a church in Osuna after the Disentailment of Mendizábal.
