 The architecture of the Collegio is peculiarly Italian in the use of the loggia, but shares a characteristic of medieval college buildings in England and France, in being arranged around a central rectangular court.Bas reliefs of the coat of arms of Spain are located above the two main entryways.The portico once had frescoes by Annibale Carracci, but a travellers guide published in 1857 reported them having "almost disappeared".
