 The castle has undergone many restorations, one as recent as 1860, and no longer retains much of its original appearance.The Colonna della Vicaria, a simple column on a pillar, once stood in front of the entrance; it was used to disgrace and punish debtors.At the rear exterior of the building, facing Piazza Enrico de Nicola, is the Fontana del Formiello.
