Catania's forbidding 13th-century castle once guarded the city from atop a seafront cliff. However, the 1669 eruption of Mt Etna changed the landscape and the whole area to the south was reclaimed by the lava, leaving the castle completely landlocked. The castle now houses the Museo Civico , home to the valuable archaeological collection of the Biscaris, Catania's most important aristocratic family. Exhibits include colossal classical sculpture, Greek vases and some fine mosaics.
