It is an area with a significant presence of mallo-type formations: the mallos de Agüero, together with the Rabosera ravine, have been declared a “point of geological interest” (P.I.G.) in Aragon.
A mallo (Aragonese term widely used in Spanish) is a vertical geological formation. They are characteristic of the Ebro valley and the rest of the Pyrenees.
The Mallos de Agüero rock formations rise more than 200 m above the village, giving it a picturesque look. The Mallos are popular with mountain climbers and abseilers.
The parish church of El Salvador in Agüero dates from the 12th century. The original construction, in Romanesque style, the work of the Master of Agüero, consisted of a single nave with two sections covered with a pointed barrel vault and a semicircular apse and was reformed in the Renaissance period, giving rise to a heterogeneous complex, in which they combine the ashlar with masonry and brick.
The reforms consisted of the construction of a straight chancel, the extension of the nave with two more sections to the west, the addition of four lateral chapels on each side. The chapels on the southern side also have an underground crypt-chamber.
Church of Santiago, declared a National Monument in 1920.
