Mirabella Fortress, Medieval fortress in Omiš, Croatia.

Mirabella Fortress, also called Peovica, is a Romanesque fortress on a rocky height above Omiš in Split-Dalmatia County, Croatia. It was built in the 13th century by the Kačić family. Its position above the Cetina gorge gave the Omiš pirates a retreat they could fall back into.

Mirabella, also called Peovica, was built in the 13th century above Omiš by the Kačić family in the Romanesque style. It served as a hideout for the Omiš pirates, who withdrew into the safety of the Cetina gorge. A legend holds that in 1537, during an Ottoman attack, the defenders' shouting and gunfire made the Turks overestimate their numbers and flee.

The name Peovica is the local Croatian name for the fortress, while Mirabella appears in older records. The site is tied to the Kačić family, who built it in the 13th century, and to the Omiš pirates who used it as a hideout above the Cetina gorge.

Access to the fortress is through a steep walking path with stone steps and a metal ladder, taking about 15 minutes. Good footwear and water are important since the path is exposed and can be in direct sun.

The 1537 Ottoman attack on Omiš is remembered in local legend: the town's defenders shouted and fired so heavily that the Turks overestimated their numbers and fled. The story is tied to Mirabella, the Romanesque fortress above the town built in the 13th century by the Kačić family.
