The Church of the Holy Trinity is one of the oldest preserved in Ourense. Originating from the 12th and 13th centuries, it has undergone numerous modifications throughout its history. Its access gate from the Plaza de la Trinidad stands out, with figures that give a good account of the temple’s history, linked to an old pilgrim hospital.

The church is the oldest of those preserved in Ourense: its atrium, in which a beautiful Plateresque-style cross (15th century) can be seen, was built over an ancient Roman necropolis.

From the original structure, the fortified appearance and some Romanesque details can still be appreciated, although the decoration of its apse, with Gothic-Flamboyant cresting, indicates that it was reformed in the 15th and 16th centuries. On the exterior, two cylindrical towers give it a certain fortress-like air, something it shares with the Cathedral. Inside, with a basilica floor plan, the polygonal main chapel stands out, covered with ribbed vaults with profusely decorated keystones. The longitudinal nave is covered with a false vault and divided into sections by pointed arches. Two Baroque altarpieces on the sides and a larger one from the 16th century in the central nave make up the sculptural ensemble, which is completed with a twin holy water font.
