After the Angevin period, Muro Lucano's castle saw long feuding by the Orsini family until the end of Italian feudalism in 1806. In the eighteenth century, after the earthquake of 1694, the Orsinis made profound changes to the manor by raising the ground floor, knocking down the drawbridge and building a new building leaning on the two towers. The 1980 earthquake necessitated an extensive consolidation process. The part called the prince's apartment had recently been restored.
