Mirabella Fortress (Peovica) is a fortress located above town of Omiš in Split-Dalmatia county, in Dalmatia, Croatia. Mirabella or Peovica is a Romanesque fortress, built in 13th century above the town of Omiš. Mirabela was a reliable hideout for the Omiš pirates who used to retreat into the safety of the Cetina gorge. Legend says that in 1537, during an attack by the Turks, the defenders of Omiš confused the attackers with their shouting and shots so much that the Turks overestimated the number of defenders and fled.
