The ancient site of the archiepiscopal curia was located next to the Cathedral on the Girfalco hill, but was destroyed during the siege of Frederick Barbarossa. In 1391 Antonio de Vetulis, bishop and prince of Fermo, built the first nucleus of the new palace next to Palazzo dei Priori.
In 1741 Archbishop Alessandro Borgia, as the plaque on the outside still states, wanted the decoration of the entrance with Istrian marble and the closure of the courtyard with a gate.
Inside are the archiepiscopal’s apartments and works of art such as the Translation of the Holy House of Loreto attributed to Pietro Testa.
