This temple is a showcase of Romanesque architecture, easily identifiable by its robust walls, torn only by small crevices, by its round arches framing the portals, by the corbels richly decorated with zoomorphic and vegetative motifs, and, mainly, by the bases of the columns and the beautiful capitals that support the chancel’s arches. The front portal is decorated with a very well-crafted Agnus Dei (Lamb of God), while on the side portal we find an important inscription referring to the Consecration of the Church, which took place on March 22, 1237. The nave is covered by a roof coffered with floral and religious paintings, but it is the chancel that deserves all the attention, covered by a stone vault with a rather broken arch. The high altar is in gilded wood carving, as are the superb altarpieces on the nave’s side altars.

The Romanesque Church of Arões is the only National Monument in the municipality of Fafe.
