Šabac Fortress
Mačvanski okrug
Šabac Fortress, originally known as 'Zaslon' or 'Sava' and called 'Bogur Delen' by the Ottomans, is a significant fortified structure located in modern-day Šabac on the banks of the Sava River. Built in 1471 by Isa-beg Isaković following the Ottoman architectural style, it features a star-shaped layout with a roughly square base and two round towers at opposite corners. The fortress was strategically designed to defend and control the river border, particularly to flank enemy movements. Although the northern half of the fortress was lost to the Sava River over time, the southern part with its walls and towers remains. Historically, the fortress changed hands from the Ottomans to the Hungarians in 1476, who stationed Serbian Šajkaši troops there until its recapture by the Ottomans in 1521. The fortress is a rare surviving example of Ottoman river fortifications and reflects the military and cultural history of the region.
