The walls will be restored using sandblasting. The authorities will allocate 20,000 euros for this. The last restoration work was carried out 15 years ago.
The fortress walls were built mainly in the Byzantine era, between the 7th and 9th centuries. However, their current appearance is largely the result of the influence of the Venetian Republic from the 15th to the 18th centuries. Proof of this is the large bas-relief with a coat of arms in the form of a winged lion, the symbol of Saint Mark, the patron saint of Venice.
The walls were also repaired during the Austro-Hungarian Empire. The citadel, as a separate fortification within the city, had special significance in that period. In addition to wells, residential buildings, and military units, the fortress also contained secret underground passages and ammunition depots.
