Bari’s Svevo–Normanno Castle sits at the edge of the medieval center between the old port and Cathedral. A Roman fort originally stood on the site and remains from what may be a Byzantine Church were found below the castle. A small castle was built by the Normans in the 12th century and enlarged by Frederick II in the 13th century. During the 16th century, Spanish rulers turned the castle into a royal residence and added bastions and other features.
The Castle is used for art exhibitions and there is a small permanent art display and plaster museum inside.
