Serbia: Fortresses and Castles, a Crossroads of Empires and Religions

For Browsing

On the territory of modern Serbia lie the ruins of fortresses built in strategically important locations — near rivers, trade routes, and the borders of former empires. Constructed to protect cities, estates, or monasteries, they played a significant role in the military strategies of medieval rulers. Some of the fortresses served exclusively defensive purposes: here you can explore ancient military camps, arsenals, and barracks. Inside others, entire towns grew: houses, schools, and shops, as well as churches and mosques. The ruins of some of them have been preserved to this day. One of the oldest fortresses in Serbia is Stari Ras, listed as a UNESCO World Heritage site along with the nearby monasteries of Sopoćani and Đurđevi Stupovi, as well as the Church of the Holy Apostles Peter and Paul (Petrova Church). Serbian fortresses allow you to connect with the turbulent history of these lands and transport visitors back to the Middle Ages — a time when powerful rulers, brave knights lived here, and major battles took place.
