In the Hall of the Barons there was the epilogue of the famous Conspiracy of the Barons, war against the King Ferdinand I of Naples, son of Alfonso V, by many nobles, led by Antonello Sanseverino, Prince of Salerno, and Francesco Coppola, Count of Sarno. In 1486 the king invited all the conspirators to this room under the pretext of a wedding party, which marked the overcoming of hostilities and definitive reconciliation. The barons ran, but the king, ordered his soldiers to bar the doors, had them arrested, punishing many of them, including Coppola and his sons, with the death sentence.
