The Trinidad complex, consisting of the palace of the Jove Huergo family and the adjoining chapel, was built in the 17th century.

The palace is made up of two juxtaposed rectangular buildings divided into three floors. In both bodies there is a symmetrical distribution of openings and the floors are separated by a line of imposts. A coat of arms with the arms of Hevia, Miranda and Lavandera, located in the central axis of the building, is the only decorative element on the façade. Attached to the palace is the chapel, with a single nave floor plan, divided into two bays. The façade supports a monumental Baroque façade, structured by a linteled opening with moulded pilasters. Above the lintel, a panel houses the Jove family coat of arms and is crowned by a semicircular pediment with a lunette that illuminates the choir.

The façade is finished off with a graceful belfry topped by a curved pediment. Both the front of the palace and the chapel are of good ashlar.

The interior of the nave is covered with a groin vault, and the chancel has a dome on pendentives decorated with the figures of the four evangelists. On both sides of the chancel there are two stone niches topped with a split pediment.

The Trinity Chapel was restored in 1963, and in 1989 the whole complex was refurbished as the Juan Barjola Museum.
