Fodor's Expert Review Castello Svevo
One of Frederick II's most imposing fortresses, the quadrangular Trani Castle guarded the Adriatic sea route throughout the Middle Ages. It was the scene of several royal weddings of the Swabian and Anjou houses, as well as the place of imprisonment for life of Siffridina, Countess of Caserta, who had supported the losing Swabian dynasty against Charles I of Anjou. In the early 20th century it became a state prison and remained so until 1974. The ground floor contains a museum telling the story of the castle alongside archaeological finds, sculpture, and a wealth of ceramics.
