This late 18th-century Main Church has a façade with a late Baroque doorway, a triangular pediment and three large windows which provide good illumination of the inside.
On the roof of the church, the main feature is the imposing dome surmounted by a false lantern.
On the inside, the principal features are the altarpieces in the neoclassical style, a statue of the archangel São Miguel (St Michael) (15th century), a statue of Nossa Senhora dos Mártires (Our Lady of Martyrs) (16th century) and some others dating from the 18th century, including one of Santa Luzia.
