Doric order
The main facade, oriented at noon, has two front doors, one entrance to the college and the other that gives way to the church. The first is of Doric order, in ashlar, with royal shield, and another with the arms of the founder. The second has two bodies: the lower one, with a half-point span framed by four pilasters in Doric order, and on which is seen a shield with arms of the Cardinal Silíceo. Both portals are Baroque classicists.
