It was founded in 1583 by Bishop Antonio Mauricio de Pazos y Figueroa on the same site where it now stands, although in the beginning the facilities were more modest. It was extended in the 17th, 18th and 19th centuries.
At the end of the 17th century it incorporated the chairs of Philosophy and Theology and, in the 19th century, the canons of Latin studies, thus completing the ecclesiastical studies.
During the French occupation it was used as an artillery base and, during the Civil War, as a barracks and blood hospital.
Today, it is the residence of the bishop and senior priests, while the training of seminarians has been moved to another building in the north of the city.
