Although this lava stone castle dominating Piazza Umberto was built in the early 14C, its foundations go back to the Norman period. It is now home to a museum with three sections: an ethno-anthropological museum (local crafts); an archaeological museum, tracing the region's history from the Neolithic to the Byzantine period (note the Banchettante, a small bronze piece from a workshop on Samos, and a beautiful crater bowl on small columns from Attica); and an art gallery exhibiting paintings, artefacts and sculptures from the 17C-20C.
