In 1563, the Council of Trent initiated the reform of the Catholic Church on the basis of a more solid formation of the clergy to be implemented with the establishment of the seminar.
This building, built between 1567 and 1573 and enlarged in the 17th century, was the seat of the bishop’s seminary for two and a half centuries, now instead located on the opposite side of the Upper Town on the hill of San Giovanni.
It is entered through a Baroque portal from 1689, and the inner courtyard has a high portico with a loggia above.
