The Patriarca, Real Colegio and the Seminario del Corpus Christi are a church, a seminary and a college respectively.

Work on the buildings began in 1586 and finished in 1610. It is structured around a large renaissance cloister enclosing the church, the communion chapel, the library, the sleeping quarters and the classrooms. There is another courtyard at the back and a small belfry is located in the corner of the plaza.

The museum displays valuable works of art by El Greco and some primitive Flemish paintings.
