Ursino Castle or Castello Ursino is a medieval
stronghold situated in Catania in Sicily Island in the Southern
Italy. The citadel was constructed between 1239 and 1250 upon orders
of Emperor Frederick II, king of Sicily. Ursino Castle was a key to
keep a royal presence in the region. Many other private castles of
the local feudal lords were demolished to keep the crown happy.
Today Ursino Castle or Castello Ursino is open to the public. It
houses a Catania Civico Museum and a gallery of Sicilian art.
