Isar Fortress
The Isar Fortress is situated on a steep hill, 150 meters high, overlooking the confluence of the Bregalnica and Otinja rivers in the city of Štip. The remains visible today mostly date back to the 14th century, when the despot Hrelja reinforced the structure under the reign of Tsar Stefan Dušan. Archaeological research, however, proves continuous settlement since the early Iron Age and the existence of a late Roman fortification known as Astibo. The citadel walls enclose an area of approximately 0.6 hectares and were constructed using quarry stone and lime mortar. Several churches were originally located within the complex, including the Church of Saint Archangel Michael, whose ruins are still partially preserved. As a strategic control point, the fortress secured access to the central regions of North Macedonia and played a key role in conflicts between Serbia, Byzantium, and the Ottoman Empire. Today, Isar is the most prominent historical landmark of Štip and has an extensive view of the modern cityscape.
