The Church of Santo Estevo de Sandiás is of late Gothic style, rare in Galicia, built by Bartolomeu de Nosendo before 1520. It has a single nave and quadrangular presbytery.

It stands out for its interesting Manueline style cover and a complicated set of archivolts and arches. It has two arcades: the inner one has a lowered and broken arch in the middle, formed by a narrow baquette on small columns of the same diameter, with small capitals of delicately sculpted serpentine leaves; the exterior has a smooth lowered arch.

Outside the arch, the batons come out and break forming five points, four of them ending in pointed rosettes and the central one supporting an image. Inside, the main arches rest on tall columns attached to the walls, whose capitals have Renaissance motifs.

In the apse we find a cornice topped by a narrow parapet, with three-lobed leaves resting on corbels. The 17th century altarpiece is of great importance due to its significance in the art of Ourense of this century, and in the work of Francisco de Moure.
