The fortress was originally commissioned by Isa-Beg Ishaković, the founder of Sarajevo.
In 1476, the Hungarian King Matthias Corvinus captured the fortress after a brief but intense siege.
The original fortification was built using wooden structures and earth, later reinforced by masonry as it gained military importance.
The site was officially demilitarized in 1867 when the Ottoman garrison withdrew from the city.
It is situated on a location historically referred to as Zaslon, predating the modern name of Šabac.
Šabac Fortress, also known as Zaslon, sits on the banks of the Sava River and represents a strategic point in the history of the Serbian-Ottoman frontier. Originally constructed by the Ottomans in 1471, the fortification served as a base for military operations across the river. It was frequently contested, changing hands multiple times between Hungarian, Ottoman, and Serbian forces throughout the centuries. Today, the site consists primarily of earthworks and remnants of the defensive walls following the destruction of the main keep in the 19th century. Excavations have revealed layers of occupation dating back to the medieval period. The area is now managed as an open-air historical site within the municipal park space. It remains a key landmark for understanding the geopolitical evolution of the Podrinje region.
