In the fortress there are also the marble fireplaces designed by Orsi himself and some of the original coffered ceilings as well as furnishings, ceramics, coins and pharmacy jars, which constitute a valuable collection of about 170 pieces, some dating back to the XVI-XVIII century. In the first room there are three fragments of frescoes dated 1280, coming from a destroyed local church. In the gallery of portraits there are eminent personalities of the dynasty: from Camillo I to Philip Alfonso; from Vittoria of Capua to Matilde d'Este.
