Valjevo Fortress

Kolubarski okrug

Valjevo Fortress, locally known as Jerinin Grad, is a medieval fortification situated on the western slopes of Branig Hill in the village of Brangović, approximately 5 km south of Valjevo. The fortress occupies a steep rock above the Gradac River and features extensive remains including a donjon tower and long defensive walls that descend the sharp hillside. It is the largest fortress of its kind in northwestern Serbia, covering about 3 hectares. The fortress walls were constructed from hewn stone and lime mortar, strategically positioned with natural cliffs and the river providing defense on multiple sides. Archaeological research reveals that Jerinin Grad was originally established in the 4th century as an episcopal seat, evidenced by remains of an early Christian church with an episcopal throne. The site underwent multiple destructions and reconstructions during barbarian invasions before being abandoned in the 10th century, possibly due to Serbian-Hungarian conflicts. The fortress's architecture aligns with early Byzantine military traditions, suggesting construction or significant renovation during Emperor Justinian's reign in the 6th century. Located along an important historical route connecting Sirmium with mining regions and Dalmatia, Jerinin Grad was a regional center likely linked to trade and metallurgy. The settlement inside the walls was well-developed, with ruins of a church dating from late antiquity and additional buildings, indicating a vibrant community. Today, the fortress remains a compelling archaeological and cultural site, reflecting the layered history of the Balkans from late antiquity through the early medieval period.
